Younger than that for me. As kids in elementary school my friends and I used to ride our bikes to the gas station at the entrance to our subdivision. They only had like one rack of candy bars and a soda vending machine, but for a 10 year old with some change in his pocket that was great.

This was the mid-1970s.

There was a larger "convenience store" at the other end of the next subdivision, you could bike to it but it was a few miles so we went there less often. They had a lot more snack choices though, and you could get a glimpse of the covers of the Playboy magazines that were on the shelf behind the counter.
