Heck, back when I worked at gas stations they hadn't even considered self-serve, they were all full-service. I remember fighting with the other guys to wash the windows every time a hot chick pulled up to the pumps. Bragging rights went to any of us who washed the windows of those wearing short skirts. Funny how the drivers side of the windshield always required extra attention...I am old enough to remember full-service and self-service at the gas station, heck I even worked at an Amoco that offered both. But remember, when that transition was coming through, self-service was at a discounted price.
