Plus: - the attendants do multiple cars at once, up to 4 or so. while one car is filling, they go to another car at another pump. - probably less than 1 minute of "work" per fillup (the rest of the time is just waiting for the tank to fill) During peak busy periods I think the gas station attendants probably do 50 cars per hour each
