Let's say, outside of tourist zones.
And, yes, I recognize that there are 50 countries in Europe as different as Mexico City and New York City, so the answers will not be yes or no.
Some years back I wanted to have a better understanding in Hungary so I played Sherlock Holms. I came to the understanding that here there is no socisl pressure to tip. But like there is no social pressure to give your metro seat to an elderly person, it is looked upon as a reflection of the individual.
How much? Rounding up to the next 500 ft (that is a paper money value, keeping change out of my pocket) on the small bills and cab fare, and a maximum of 10% on the larger bills seems to be the norm. I like 10% as its easy to calculate, then I round up or down to the nearest 1000ft depending on the service and the size of the bill.
Then came the claim that if not for Americans in recent years the tip wouldn't exist. I searched some more. I found two documented discussions, one dating to WWII, the other to about 1900. The most interesting was the 1900 letter from an English gentleman living in Budapest to his son in England. He advised his son that tipping was the norm in Budapest ... and 10%.
People want to conflate this with a living wage. For that to be the case, since the living wage concept is new, one would have to know if the living wage somehow put an end to an existing culture of tipping or if there was no tipping culture prior to the living wage. I think this is more of a cultural norm and less of a situation of income .... at least as often as not.
But if you want to talk about living wages as they relate to tourism, that's fine, the OP says it's on topic. Since the purpose is understanding cultures, I would hope the discussion would be other than judgmental.
