Sorry, I've lived my whole life in Europe in three different countries and have never been to a café where you can't pay in cash and don't tip. Tipping works differently, e.g. in my current country of residence you leave cash on the table, but unless your bill is very low (say, below 5 EUR) not tipping is still a bit rude. There used to be no tipping at all but with the increase in tourism that's no longer the norm.
