As a European, this whole concept is mind boggling. Just show me a price for a service or an item, and I'll pay it. The listed prices for us already include any taxes and charges. If you're having a nice meal and you're satisfied with the service delivered you can leave a little extra. But there's no pressure or expectation to do so. I remember visiting NYC and being baffled by how the hamburger listed at $ 5 ends up costing $ 12 in the end.
