well...servers get tips, so that's incentive to serve well. it could be viewed as a commission in a sense.
as for retail, there are small retail stores that work on commission, but gas stations usually have enough sales in the convenience end of it to not have to worry about sales. A friend of mine runs a gas station/convenience store/Subway restaurant and makes WAY more on the consumable products other than the gasoline.
To be completely honest, I wouldn't want a full commission pay rate at these types of businesses because there's days that are horribly slow as well as the days where you're swamped for your whole shift. If the commission was additional to the pay, I could understand, but I wouldn't want to base someone's pay wholly on the spending of customers because you'll always have uninterested people.
