Don't some places split the tips between all the staff including the buspersons (boys, whatever)? I swear I knew someone who said the place she worked even split it with the cooks.
Fortunately, I never had to wait table. I did a LOT of tutoring and typing, in and out of the classroom. Nothing like being 21 and have some gigantic football dude break down in tears because he's having problems with his writing skills. Whew boy, you learn about others' challenges really, really fast. Really, really.
