Interesting. I had a taxi driver in Hamburg bitch at me for the whole ride that Americans don't tip and why don't they tip?

So, that was the one taxi ride in Germany I took and didn't tip. (It was not the first taxi ride in Germany.)

Maybe there's an east-west divide? My experience is with Berlin.

Looking at a few sites this morning, it sounds like it's typical to round up to the next Euro in Germany, and that tipping more than 10% might be seen as offensive (unless of course you are hoping to get some extra from an American).
