In my neighborhood, the pizza guys are taking their lives in their hands every time they get out of the car. Most of the shops won't even deliver to my street. I tip the guy at least 3 bucks, and more when I have it. Most of the a-holes around here just take the food, wait for every last penny of change, and then slam the door in their faces.
It might not seem like they are doing much for the money, but they are using their own vehicle. Gas, oil changes, tune ups, tires, wipers, batteries, etc. and insurance costs alone pretty much wipes out the piddly minimum wage paycheck these guys earn. And then they have to save a big chunk for when the car breaks down (and it WILL break down). And then driving a car like that (stop and go) 8-12 hours a day for a couple years will destroy any vehicle the poor slob can afford in the first place, so factor in the cost of a new car every couple years. I really really can't understand how these guys make any money at all. I never could

With that said, if I'm too lazy to get my fat ass off the couch and cook something, I'll gladly pay for the priviledge to have it delivered.
