They have become gas stations or filling stations. Rarely do you see "service stations" anymore. My small town her in SC still has one service station which I religiously use. When I drive up to the pumps an attendant comes out and asks me which grade of gas I want and if I want a fill-up. Once he starts pumping the gas he asks if I want the windshield cleaned. They even still ask if I want my oil level checked. Their gas runs about 3¢ above the average for other stations. I've heard people say they don't use the station because the gas cost is too high. Really? I drive a Toyota Tundra 4x with a 38 gal tank. If I'm flat empty, which is never the case, the difference in a fill-up is only $1.14. That's a small price to pay for full service. I never have to get out of my truck.
Was in Oregon maybe 15 years ago - before they did away(?) with their law. The "attendant" came out, asked which variety and how much gas I wanted and went to it. I asked if he could do the windshield, and was met by a blank stare. I got out and looked, but no buckets or squeegees. I asked him why Oregon required an attendant to pump gas, which was also met with a blank stare.
The "attendant" was barely sentient, and looked incompetent to identify and trip a shut off switch - kind of negated the "for safety" argument for having attendants in the first place.
