Where I work there are 4 gas and 2 diesel pumps
The gas pumps dribble in cold weather, refusing to pump full speed. If you lift the nozzle high, wiggle it around , sometimes it will release the bubble (assumed) that was triggering this behaviour. If you leave it to fill while dribbling, the flow sensor does not work, overflowing forever.
The EPA loves us.
The gas pumps have a breakaway connector that stops the gas if you drive away while pumping. Done it a couple of times. The diesel does not, and will spew the fuel if ripped off. Seen it.
Sometimes the diesel does not shut off and will overflow. It pumps so fast it will pressurize the tank and erupt like a volcano (unlit thank spaghetti monster) for about 5 seconds. Covered me once.
