How much do you tip?

[LaterBloomer]

In Germany, I think it was called something like "stimp so." (Off, I know.) I think the translation was "round it up." The waiter would round up the bill to the next frank (I'm dating myself), and give you the change. As I recall, just about EVERYONE went to some sort of training. Waiters. Shoe salespeople. Etc. You dealt with folks who were professionals, not just folks who were grabbing at a job that paid.
