I'm fueling my vehicle at a convenience store pump when a lady pulls up to the other side and proceeds to fumble around with the fueling equipment clearly at a loss in it's workings. So, like a good samaritan, I offer to assist. Unbeknownst to me the previous patron was lazy and had shoved their gas cap into the trigger. I pulled the nozzle from the pump and flipped the switch only to have gasoline come spewing forth in the direction of the lady, soaking her in gas from the neck down.
