JDuece just reminded me of my earliest gig. Age 10-11 my friends and I would wait for housewives or older people by the exit of the supermarkets. When they emerged we would offer to carry their bags and load their groceries into the trunk. The tip was a nickel or a dime. It was the early 70s and I wanted my DC comics and baseball cards, so that's what we did. Took away from wiffleball and boxball time though.
