I’ve had this thought for a while. I don’t know how big of an issue loss from theft actually is, but if you own a store and perceive it to be a major issue, why give the customer access to anything? You could make it distopian and shitty like you’re saying it could be, but honestly, if you do it right it doesn’t have to be. Reorganize the store so the customers can see what is available, but they get a code or ticket instead of the item. Then have the employees pick the items once the customer is ready to pay. We already have a counter serve model like this for a butcher or baker. Convenience stores do this for highly regulated items like cigarettes and liquor. Just do it for everything. If that was the premise from the start, I wouldn’t mind because it would be less hostile. The current half asses model of I pick most of my stuff, but then I have to call one of 2 pissed off overworked employees to unlock the other half individually is hostile to the customer and the employee.
