A filling station attendant or gas station attendant (also known as a gas jockey in the US and Canada[1][2]) is a worker at a full-service filling station who performs services other than accepting payment. Tasks usually include pumping fuel, cleaning windshields, and checking vehicle oil levels. Prior to the introduction of self-starting vehicle engines, attendants would also start vehicle engines by manually turning the crankshaft with a hand crank.
In the United States, gas jockeys were often tipped for their services,[3] but this is now rare as full-service stations are uncommon except in New Jersey, 16 “urban” counties in Oregon, 4 cities in Massachusetts, and the town of Huntington, New York, where there are laws or restrictions against letting customers pump their own gasoline.
