Be sure to tip your waiter or get arrested =)

Often, when dining with a large group I find the need to run back and put a few extra bucks on the table.  Seems the problem is some people estimate their share a little low.

It's always appreciated as well. Personally If I see a table doing math trying to figure out who owes what, I usually offer to split the checks for people... or they tend to forget the taxes.
