Normally here they hand you the device and you put in tip, then insert the card yourself, hit okay, enter your pin, and get the receipt, and then hand it back.

I thought it was super sketch when a waiter wanted to walk off with my card in the US. Besides that，how am I supposed to know they charged the percent tip I wrote on the receipt vs another number except by looking at my bill days later? I'm much happier being in control of the payment.
