Maybe when you come to Europe adjust to the culture.
We're in the middle of a thread in which hundreds of Europeans are complaining about American culture, which is to tip at restaurants. In fact, the original post I responded to was:
It’s crazy that this still happens in the US. Tipping is a thing of the past. Pay for your meal and have the restaurant pay their people for their work. End of story.
I think it's a little ironic that when an American complains about European culture — which is to be slow — suddenly there's a bunch of tut-tutting from Europeans about "adjust to the culture" (and you're not the only one!).
We're in a thread where people are debating the relative advantages of different cultural practices. I think America's practice of tipping has distinct advantages that make it better. And no, you're not "eating with the clock in your hand' or whatever in America: is just that when you want the check, you get it.
