Not sure how common they were, but I remember putting fuel in cars 30 or so years ago here in the UK by feeding £1 and £5 notes into the pump. It might even have taken a tenner! The garages which had these pay-at-the-pump models generally only had two of them and for some reason only enabled them after they closed for the night.
