I am not an old man, but I remember the days when I would go to the gas station, start pumping, and be able to slide in the "hold-open clip" so that I could relax my hand.
There safety hazards are obvious (although I can't recall ever hearing of anyone getting injured at a gas station, was/is it common at all?). However, surely there is a cheap design that can sense (most likely mechanically) that everything is "safe"
