Does anyone remember the thread a while ago where the OP witnessed someone putting something (crisps?) in their bag and being 'challenged' by a member of staff?
People were falling over themselves to point out that if they hadn't left the store then they weren't stealing, that the staff member was all shades of power hungry because they 'challenged' someone on it in front of other people, which would humiliate the individual and that should never happen to a 'customer', how being the 'victim' of that is such poor customer service.
One poster even said that the staff member could be potentially prosecuted for causing 'harm' to the 'customer' by embarrassing/humiliating them.
I think OP reported the staff member said something like "Don't forget to pay for the crisps you have put in your bag too" as the shopper was waiting to pay for other items in their hand or something.
Not to mention the fairly regular threads about sales staff and security guards harassing customers and the responses, that they'd have told them off, put them in their place, complained to management, made a fuss - do they really think that shoplifters haven't used these tactics - being an outraged customer at being accused of shop lifting - to get away with what they were doing? "I did it by accident. How dare you accuse me, a paying customer of theft"
I mean they can't win really can they, shoplifters don't announce themselves and mostly try to disguise and hide what they're doing and blend in, so they can secrete what they're stealing, the dash out the door and violence if caught is usually once they've nicked what they want, meaning that there is going to be an element of people who aren't shop lifting being observed or maybe even challenged - but people become so outraged and after blood when that happens that it's no wonder less people are challenged for it, combined with the risk of injury to the person doing the challenging.
We've kind of created this situation by being so obsessed with 'customer service' and behaving however we want as customers that it supercedes everything and anything else.
