Don’t get me wrong, the tipping system (among numerous other aspects) is a joke for customers, But it has massive benefits if you end up in the right job, in the right restaurant.
Absolutely no idea how many end up in the same situation, maybe the minority, but all the servers I met travelling (especially girls) would make many times more than anyone working the same job in Europe for less hours.
Plus, we have tipping in most European cities I’ve visited… Most waiters I know are on minimum wage and only survive via tips. Is it different for you?
