I hate leaving those types of events early. I'll always try to estimate my portion including tip and drop it on the table knowing it's more than I really owe.

I'd call em on it.

I have a friend that has an annoying habit. He always orders the most expensive things on the menu, several apps and drinks. When it comes time to pay we divi up evenly so he pays less than what he orderd and for some reason he only ever has enough to cover his portion but never tip.
