When I was a child, my grandfather ran a service station in rural Tennessee. He'd retired after a long career: welder, working on the atom bombs at Oak Ridge during WWII, then owning a service station for long-haul trucks in the early days of I-75 near Knoxville. He didn't like retirement very much, so after his retirement he bought a smaller service station within walking distance of his house and ran it mostly to keep himself busy. He did light work, oil changes and tire repair, and sold gasoline.
One of the things he offered was "full service," although even in those days it was an option. If you pulled up to the pump closest to the station, you ran over a pressure device that set off a bell inside. He or one of his employees would come out, pump your gas for you -- as much as you wanted, by dollar or by gallon -- and while they pumped it they'd wash your windows, check your tire pressure, clean your headlights, things like that. Though I was a child, he'd often let me do the parts of it that I could do, which I thought was great fun at the time.
Apparently this kind of thing
still exists in Oregon. They're very alarmed that it's becoming optional. I hadn't heard of it in years.
