Lately I've been at some finer diners in my country, and the payment terminals now have an option if you want to tip.
I've made it a rule never to tip. Even if the service was magnificent.
Out of all the things I don't want my country adopting from the US, the tipping must be somewhere in the top.
can only speak to Germany, but it definitely is pretty common to tip here. Just less across-the-board and less money than in the US, usually 1 or a couple of Euros.
