I'm not into tipping when I've visited the US, since I come from a country where servers are paid the equivalent of Fr. 20-30 ($24-43) an hour so there isn't an obligation to tip them, but that's the opposite in the US. Am I allowed to hand them large cash tips such as Fr. 1000 ($1236) or 500€ ($583)? It gets weirder: as apparently fast food places demand a tip, like really? It's getting out of hand, what's the point then?
