Europe has practically zero standards for waiting on tables, they just outright ignore you unless you chase them down personally. In america you're asked what you want to drink within 2 minutes of sitting down, in europe they don't even bring you the menu for 10 and they wont ever come back and refil your drink.
American service is far better and tipping is why.
