I was a server/bartender during my university years, put myself through school working at a higher end resto-bar. This was common knowledge for sure. Also Europeans were awful. The reason they add gratuity in SOBE is mainly for the influx of European tourists.
Correct!
Europeans are by far the worst tippers, period. Germans and Austrians are leading the way. They give like 2 or 4 cents to round up a check. lol
I know because I stayed in Austria for 2o some years.
Of course Prime says if you tip like an American (10-30%) they will look down on you.lol
Complete bullshit of course.

I tip extra for good service and that is the best way to show.
Europeans love to get good tips but don't like to tip others.
My experience as an ex Coffeehouse owner is black people's tip just as well as any other race.
Europeans truly suck even in Europe
