Self-checkout lanes were introduced to speed up grocery trips, but the machines haven’t won over every shopper. For some customers, scanning errors, confusing prompts, and repeated requests for employee assistance make waiting for a cashier the easier choice.
Discussions on Reddit and reports from NBC News have highlighted many of the same complaints, from slow machines to concerns about staff reductions. Here are nine reasons some shoppers prefer a traditional checkout lane, even if the line looks longer.

The Machines Often Create More Frustration
Self-checkout sounds simple enough: scan your items, bag them, pay, and leave. A missed scan, an item that won’t register, or an unexpected error can stop the whole process until an employee arrives to help.

Large Grocery Trips Can Be Difficult at Self-Checkout
Self-checkout can work well for a few items, but a full grocery cart is a different story. Limited bagging space, bulky products, and the need to scan and pack everything yourself can make a large shopping trip feel like more work than it’s worth.

Some Shoppers Feel Like They’re Doing the Store’s Work
At self-checkout, customers take on tasks that a cashier would usually handle, including scanning products, bagging groceries, and fixing errors. Some shoppers feel they’re doing part of an employee’s job without receiving a discount or other benefit in return.

Waiting in Line Doesn’t Feel Like Such a Problem
A traditional checkout line may look longer, but shoppers know what to expect once they reach the cashier. They don’t have to troubleshoot a machine or wait for an employee to clear an error, which can make the extra few minutes feel worthwhile.

Some Customers Want to Support Cashier Jobs
Some shoppers choose staffed lanes to support workers and keep traditional cashier positions available. For these customers, having a person handle the transaction is worth the wait, even if self-checkout appears quicker.
The Feeling of Being Watched Makes Some People Uncomfortable
Many self-checkout stations use cameras, sensors, and other systems to monitor transactions and help prevent theft. Some shoppers find the extra monitoring uncomfortable and feel more at ease completing their purchases with a cashier.
Some Stores Are Rethinking Self-Checkout
A number of retailers have changed how they use self-checkout machines, with some limiting their availability or adding more staffed lanes. Customer complaints, theft concerns, and the cost of managing the machines have all played a part in these decisions.
It Doesn’t Always Save Time
Self-checkout is often promoted as a faster way to pay, but the experience can vary from store to store and trip to trip. Long queues, scanning errors, age-restricted purchases, and waits for employee assistance can make a staffed lane the quicker option.
Some People Still Enjoy the Human Interaction
For some shoppers, a friendly greeting or brief conversation with a cashier makes an ordinary grocery trip feel more pleasant. Having someone else scan and bag their items can also make checkout less stressful, especially after a long day.
