Not a lot of fraud or identity theft from the waiter taking your card to charge your meal, no.

Probably there are some rogue waiters who try to use a customer’s card to buy personal things for themselves, but I’ve never heard of it happening to anyone I know personally

I’ve seen Americans discussing paper shredders as standard appliances everyone has because they are afraid of identity theft.

it’s like you don’t think that cultures change across the world.

This you? The guy who thought you could only pay for a bill at a restaurant via contactless? Also, the whole “different cultures do things differently” thing cuts both ways. You were assuming you couldn’t pay for a bill with anything other than your phone because that’s (maybe) how it is where you live, and when other people said it was common for their experiences to be able to just hand a credit card over to a waiter, you said “well, it’s different where I live.” Yeah, and it’s different where the people you were replying to live, too. And where they live, they hand a credit card to a waiter. But you never considered that until someone corrected you. So maybe you should consider your own cultural assumptions before calling other people out on theirs.
