If shoppers have one complaint about Costco—the vast discount warehouse chain with a notoriously permissive return policy and speedy checkout lanes—it’s that the employees posted at the exits to take a marker to customers' receipts seem vaguely insulting. Is the premise that everyone is a shoplifter until proven otherwise?
Not exactly. A 2018 rundown of Costco's policy from The Takeout (via Cheat Sheet) points out that the true motivation of these exit-door sentries isn’t to identify potential thieves. It’s to make sure that Costco isn’t picking the pockets of its customers.
According to employees who have made not-for-attribution comments, Costco is actually examining receipts to make sure a shopper hasn’t been overcharged for their purchases. Someone with three giant bundles of toilet paper in their cart, for example, might have been charged for four. By giving the receipt a cursory glance, the employee can make sure a cashier didn’t inadvertently ring up phantom crates of canned tuna.
Of course, if someone did try to wheel out several big-screen televisions without a receipt, the exit door employee would likely make an issue of it. But they’re not in loss prevention, and the measure isn’t intended to deter thieves. If you do have something in your cart you didn’t pay for, their immediate assumption is that the mistake is almost certainly the result of a cashier not scanning the item.
In fact, hardly any criminals are caught at the door—which isn't to say the store isn't immune to theft. Earlier in 2018, thieves at a Seattle Costco were busted with armloads of laptops after they barged out of the back entrance. Later, in June, a Costco in Alpharetta, Georgia, was victimized by burglars who smashed the jewelry case at night and made off with $10,000 worth of valuables.
