This is a true story, I guy I work with (He is 6' 2" tall and fit for his age, he also has a shaved head - Essex boy style), he was in his car, with his wife beside him, in a traffic jam. He saw red, when the car in front lowered the drivers window and dumped carrier bag full of rubbish onto the road. My friend - "Mr. X", got out of his car, picked up the discarded bag, opened the rear door of the offenders car and chucked the bag in, closed the door and got back into his car, only to have his wife admonish him.
Traffic moves on and grinds to a halt, offenders drivers window opens once again and the bag dropped again onto the road. Mr. XXX goes ballistic, gets out of his car, picks the bag up once again and tried to open the offenders car door, only to be thwarted by the guy closing the doors with his central locking system, and sits there laughing at Mr. XXX. Mr. XXX, then lifts the guys wiper blade and places the bags handles over the wiper arm.
The jam starts to move on, so Mr. XXX gets back into his car, only to be berated by his wife for being so foolish etc.
Cars stop again, the guy in front gets out of his car, Mr. XXX gets out of his and beets the guy to getting out, The guy stands up, and he is built like the proverbial brick shit house, Mr. XXX starts to tell this guy what a piece of shit he is, and wallop! he guy floors Mr. XXX with a right hook. He takes stock of the situation and retreats to his car (after-all, the jam was moving on....). He wife vents her spleen for the next two hours.......
But! this is not the first time Mr. XXX has seen red, but they are stories for another time.
