You’ve seen the sign. It’s right there at the entrance to the self-checkout lane. “10 items or fewer.” Sometimes it says 15. Sometimes 20. Doesn’t matter. Because the person in front of you has a full cart, a bag of loose avocados with no sticker, and absolutely zero shame about it.
The item limit at self-checkout is, by all accounts, the most universally ignored rule in American retail. It’s printed on signs, displayed on screens, and occasionally announced by a tired employee standing near the kiosks. And yet, people roll right through with 30, 40, even 50 items like the sign was written for somebody else. It’s become so normalized that most of us don’t even blink anymore. We just sigh, check our phones, and wait.
But here’s the thing — that little rule exists for a real reason. And ignoring it has a cascade of consequences that affect every single person in line behind you.
Target Already Proved the Item Limit Works
In March 2024, Target rolled out a 10-item limit at self-checkout across almost all of its roughly 2,000 stores nationwide. This wasn’t a guess. They’d tested the policy at around 200 locations first, and the results were hard to argue with: the self-checkout process was twice as fast when shoppers stuck to 10 items or fewer.
Twice as fast. That’s not a marginal improvement. That’s the difference between being in and out in two minutes versus standing there long enough to reconsider every life choice that brought you to this particular Bullseye-branded purgatory.
Target also surveyed customers and found that the overall checkout experience rated higher when the limit was enforced. People liked having the choice: self-checkout for quick trips, staffed lanes for full carts. Alongside the policy, Target said stores would increase the number of traditional lanes with cashiers, so nobody was being punished for buying a lot of groceries. They were just being directed to the right lane.
Walmart made similar moves around the same time, adjusting their self-checkout protocols. The message from major retailers was clear: the free-for-all isn’t working anymore.
One Person’s Full Cart Ruins It for Everyone
When someone ignores the item limit, the damage isn’t just about time — though it is absolutely about time. A person with a full cart scanning items one by one is slower than a trained cashier every single time. Cashiers do this for hours a day. They know the PLU codes. They know how to handle a coupon error without staring at the screen like it just insulted them.
But beyond speed, there’s a domino effect. The person with 40 items hits a snag — a barcode won’t scan, an item needs a price check, the machine locks up because something wasn’t placed in the bagging area correctly. Now the attendant, who’s supposed to be watching four or five kiosks, is stuck helping one person. Meanwhile, three other machines are flashing errors with nobody to help.
Every person who followed the rules and showed up with six items is now stuck waiting longer than they would have in a regular checkout line. The whole point of self-checkout — speed and convenience — evaporates because one person decided the rules were optional.
Produce at Self-Checkout Is Its Own Disaster
Even if you respect the item limit, bringing a pile of loose produce to self-checkout is asking for trouble. Most fruits and vegetables don’t have barcodes. That means you’re either typing in a PLU code (if you know it) or scrolling through a touchscreen trying to figure out whether what you’re holding is a Fuji apple or a Gala apple, or if that leafy green is chard or kale.
The stickers with product codes fall off constantly. And the on-screen search function at most self-checkout kiosks is about as intuitive as a 2004 flip phone. If you’ve got three or four different types of produce, you can easily add five minutes to your checkout time — five minutes that feel like twenty to the person behind you holding a single box of cereal.
Pro tip from people who’ve actually worked these lanes: if you know the PLU code, punch it in directly. Typing in “5-digit code” is always faster than searching through categories. And if you’re buying a bunch of different produce without codes, just go to a cashier. They’ll handle it in a fraction of the time.
The Theft Problem Is Getting Worse, Not Better
Here’s where the item limit conversation gets darker. Self-checkout theft is a growing crisis, and overloaded kiosks make it worse. According to a LendingTree survey, 27% of self-checkout users admitted to intentionally taking an item without scanning it. That number was 15% just two years earlier — an enormous jump.
The motivations people gave were bleak: 47% cited unaffordable essentials and 46% blamed price increases tied to tariffs. Millennials and Gen Z were the most likely to have stolen at least once, at 41% and 37% respectively. And perhaps the most surprising stat: people earning six figures were among the most likely to steal, at 40%.
The shrink rate — retail jargon for losses from theft — at self-checkout is estimated between 3.5% and 4%. At staffed registers, it’s under 1%. That’s not a small difference. It’s the kind of gap that makes executives nervous. Wegmans pulled self-checkout entirely back in 2022, citing unspecified losses. In the UK, Booths became the first supermarket chain to ditch self-checkout from almost all its stores.
Over 36 million Americans have stolen from a self-checkout kiosk at least once, according to research data. And 36% of thefts are accidental — the shopper just didn’t notice an item failed to scan. When machines are overwhelmed by someone scanning a full cart, those “accidental” misses get a lot more likely.
Cities Are Starting to Step In
The self-checkout free-for-all is starting to attract attention from local governments. In September 2025, Long Beach, California passed what’s being called the “Safe Stores are Staffed Stores” ordinance. The law limits self-checkout kiosks to 15 items and requires at least one employee to monitor every three stations.
The result? Some local stores have closed their self-checkout lanes entirely because they can’t meet the staffing requirements. It’s a real tension — stores adopted self-checkout partly to cut labor costs, and now they’re being told they need more workers to make the technology function properly.
This is likely just the beginning. As theft numbers climb and customer frustration grows, more cities and states could follow Long Beach’s lead. Retailers are caught between a system that saves them money on labor and one that’s hemorrhaging money through theft.
Scan Your Big Stuff First
Here’s a rule you probably didn’t know about: if you have any bulk items — cases of water, large packs of paper towels, big boxes of anything — you’re supposed to scan those first. An Australian shopper learned this the hard way when a store employee insisted she scan her large box of mineral water before anything else.
Why? Bulk items are among the most stolen products in stores. It’s easy for someone to leave a case of water on the bottom of the cart and “forget” to scan it. By scanning bulk items first, the system registers them and it’s harder to walk out without paying. Store employees across multiple chains confirmed that this is standard practice — even at staffed registers, cashiers are trained to ask about bulk items first.
While this particular story came from Australia, the logic applies anywhere. If you’ve got something big sitting in your cart, scan it before you start on the small stuff.
Alcohol and Cigarettes Don’t Belong at Self-Checkout
This one seems obvious but people try it constantly. If you’re buying beer, wine, or liquor, self-checkout is going to slow you down. The machine locks up until an employee comes over to verify your ID. That employee might be dealing with three other kiosks at the same time. Now you’re standing there, staring at a frozen screen, while a line builds behind you.
Cigarettes are even worse — many self-checkout systems won’t process tobacco purchases at all. The machine literally cannot complete the transaction. If you know you’re buying age-restricted items, save yourself and everyone else the hassle and head to a staffed register.
People Actually Prefer Cashiers — They Just Don’t Realize It
Here’s something interesting: a series of 2024 studies published in the Journal of Business Research found that customers show higher loyalty to stores staffed by human cashiers versus those relying on self-service kiosks. People feel more connected to a store when another person helps them check out.
And yet, 79% of consumers use self-checkout regularly. About 49% use it for most or all of their purchases. We keep choosing the option that makes us less loyal and, according to multiple surveys, less satisfied. Why? Because in the moment, avoiding a line feels like winning — even when it takes just as long.
A Wharton professor put it bluntly: self-checkout isn’t designed to make your experience more efficient. It’s designed to transfer the labor to you. The store saves money on cashiers. You do the work. And when the system breaks down — because someone brought 45 items, or the scale won’t stop yelling about the bagging area — there’s nobody to blame but the machine.
So the next time you’re heading into the self-checkout lane, do a quick count. If you’ve got more than 10 items, just go to a cashier. It’s faster for you, faster for the person behind you, and you might even have a pleasant two-second interaction with another human being. Stranger things have happened.
