Dude sometimes those scales are stupid sensitive and even straight up busted.

My grocery store keeps empty paper bags in a pile on the scale so they are part of the tare weight. Doesn’t matter. I’ve taken a bag off the pile, opened it, and placed it back on the scale…and needed to get an employee to re-tare it so I could start scanning. This was before even scanning.

My grocery store also has cameras on top, too, watching you from above. At each register. And if they think that you put something in the bag without scanning it, it’ll call over an attendant. To review the tape with you, like getting the refs to review a play.

Plus having kids that can’t stand still. Bound to touch the scale at some point. And they love to do self checkout.

BJs has it right…they are a wholesale club like Costco. I think they are regional. They have scales but I don’t think they even use them. In fact, I don’t even have to unload my cart. I try to load my cart so barcodes are all facing up (as much as I can) so I just rapid fire zap-zap-zap. It’s very satisfying.
