Then you will “love” to know that they can still charge the card after they have swiped it. I was floored when I noticed it. So you give the card and then they come back with your card and a new bill that has a place for you to write down how much tip you wanna add. You do not give your card again, you just leave the paper in the table and they will add the amount to what they are gonna charge your in your cc. This would not fly in my country, I am actually shocked that cc fraud is not more widespread in the US with how “low security” it all seems. Once I when to buy something and I head forgotten my cc PIN (because now always using contactless pay and such", the person handling the register told me I can skip it, and sure enough, there was an option on the machine to skip entering the PIN. I guess the PIN stuff is new in the US and people are not used to IT so it is not even a red flag to say that you do not know your own PIN and they even have the case built-in in the software. Shocking.
