A friend of mine works at a gas station..and this is a real life story, the first part which he witnessed and the second which was retold to him.
My friend works as a cashier at a gas station. A man had just finshed filling up his car, which i believe is an infinity. My friend looks at the car and notices it moving, he tells the man"hey your friend is moving your car from the pump." The man says "I don't have a friend with me". He turns around to see another guy driving away with his car, he had been unlucky enough to leave the keys in the ignition. They chased after the guy but he got away.
So a few days ago the guy came back to the gas station to finish off the story. Apparently since the time when the car had been stolen he had been driving he wife's car. He was parking at a local mall when behold his stolen car was parked right next to him, plates and all. He waited patiently for the man to return and proceeded to kick his ass. The man was left pretty roughed up and more then a little bloody. He then took back his car keys and drove away. No police were involed, just two fists as justice.
