if people tips too much, pizza delivery will get rich real quick for only delivering pizza. Compare to other people who work much harder but get pay less and "more dangerous job."
ADD: My sister work in a factory making carpet when she accidently put her foot in a machine. It cracked her bones. She worked there for 11 months and the accident happen. She was sent to the hospital and they have to open up her foot and put screws on it. She can\'t move her left foot for two months when the doctor finally open it up again and remove the screws. And she make like $8 an hour. Can\'t remember because she live in Georgia and I live in CA.
