"It's never rude to tip in Europe," adds Masty1992 on a Reddit forum (caution: some strong language). Indeed, many Americans weighed down by 'tip fatigue' deliberately visit countries where gratuities aren't expected. Another reason you might decide not to tip is the "service charge," which is normal in restaurants across the continent. You shouldn't be surprised if your dinner bill in Europe has this sneaky extra charge, and Americans might have mixed feelings about it. Others might appreciate the service charge, because you don't have to publicly assess the waitstaff's performance; if you really don't a like the hospitality, just don't come back.
