Just when I give the benefit of the doubt

A guy I know told me how he was waiting patiently in line to get up to the pumps and right when he finally had his chance to do so some ahole zips in front of him up to the pump.

His buddies in the car with him are telling him to get out and kick the guys ***, but he says no just wait. The jerk finishes up pumping gas and goes inside to pay up. That's when this guy gets out of his car, takes his locking gas cap and puts it on the jerk's car.

He's out his locking gas cap but the thought of what will happen the next time the jerk has to fill up is priceless.
