Something Pup posted t'other day about Americans and rules reminded me about the one instruction that they just don't seem able to follow:
Not valid unless signedSeriously, a huge proportion of Americans use credit and debit cards every single day that are unsigned. This is considered normal. When I asked why, I was told that signing your card was a fraud risk because then people would be able to copy your signature. When I pointed out that I can scribble anything I can easily reproduce on an unsigned card and suddenly it looks like it's mine, it didn't change any minds. Bonkers, I tell you...
Being the smart people that you are, you will of course have realised by now that this means American shop assistants don't check signatures. You're right. In fact, normally, the signature is entered into a touch-screen pad and the cashier never sees it. There's virtually nothing to stop a stolen card being used in stores here until it's reported stolen. Then of course, you just have to take it to a small store that does off-line authorisation and it's good for a couple more days as well

Does anyone here work in retail? Ever been given one of these cards by an American tourist? My mother has a couple of tales to tell about people who got terribly rude when she pointed out that the notation "Not valid unless signed" meaned exactly what it said and that she wouldn't be able to take that card and "No sir, if you sign it now in front of me, I still can't take it"...
So yes, Americans love their rules and regs but they have a tendency to ignore that one.
