Do American supermarkets really have somebody to check your receipt when you walk out?
From what I have seen it varies depending on where you are
The USA is a rather big place - which we tend to forget!
I don;t think it would work here - we have very firm privacy laws and tend to get rather awkward
I remember during Covid was went shopping on my bike and so had all my stuff in my backpack
the Self Scan thing came up with a check
so I waited for someone to come over
it turned out to be someone I used to work with when I was a teacher (she was a TA and gets more working on the ills in Tesco!!!)
I took some things out of my backpack for her to check and she said "OK"
"funny thing - I am not allowed to check your backpack as it is a closed bag!!"
also makes to laugh when we go to the cinema
if I have a backpack they want to check it
but my wife can wander in with her handbag - which is nearly as big as my backpack - and they cannot ask to check it
so we put the drinks and sweats in that!
