That'd be cool, free gas! I've seen a couple that didn't shutoff when the tank was full. That's a mess! And, a couple that allowed the previous guy to set the nozzle to on so that the next poor slob (me in this case) got a hose that started delivering gas just as soon as the pump was turned on (before putting the nozzle in the filler pipe).

I guess I'm happiest when the things work the way they're supposed to.
