On nozzle locks not always working:
Oh, the nozzle locks usually hold okay, except for once in a while when one would break and then you'd have to stand there and hold the cold metal nozzle for the entire fill (and, no, it was hard to manage with gloves on, so you'd take the pump hand glove off, and you didn't want to soak your glove with gas either)....it's the safety shut-off valve that's supposed to kick-off when the tank is full that has a habit of failing.
And here's a tip for all you self-service pumpers...it's a good idea to stand off to the side, and not in front of the tank opening, while you're pumping, and especially when you start to pump, because a lot of model's tanks have a way of burping up a nice splash of gas at the outset, especially if you release too fast a flow at the outset which most folks are prone to do. Gas baths are no fun...believe me.
