Ever since I delivered pizzas out of high school my tip has always been $5. My average tip back then was maybe $0.50. That is if they didn’t want exact change back. Someone called in because I didn’t have a dime for thier change, and had to have them give me $0.15 back in the quarter I had. I got in trouble for that because i told them I didn’t have the dime, and if that was OK. They called in saying I demanded a tip.
