My local grocery store self checkout after every single item:
Unexpected item in bagging area.
If they're going to treat me like I'm stealing the groceries I'm paying for, making the process slow and inefficient, then I'm just going to go to the regular checkout and not deal with it.
I find it fascinating around here that all the self checkouts do that except Walmart which is actually pretty good. I usually go to the cashiers at other places because the self checkouts suck, and the cashiers bag stuff better than me.
Walmart's self checkout probably doesn't accuse you of stealing out loud. They want to wait until they can "prove" you've stolen over $1000 worth of goods over time so they can charge you with - I forget - either grand larceny or grand theft, which are felonies.
I hadn't thought of that but that could be the case now that you mention it. I'm not stealing at any of the self checkouts, the grocery store ones though around here always think something got placed in the bagging area that wasn't scanned which isn't the case. I guess Walmarts just dont care which I like.
Cub foods has the worst self checkouts around here, unless I'm only buying under 3 items I won't use it. They also don't bag your items though if you go to a cashier, all around just kindve a shitty shopping experience at Cub.
