Tired Mechanic and Bikers

This mechanic was really tired and pulled into a diner, and just ordered a cup of coffee. While sitting at the counter, a group of bikers pulled in, started acting rowdy, spilled his coffee, made fun of him, and tried to pick a fight with him. He just got up, paid for his coffee ,and walked out and drove off. One of the other customers said to the waitress: “My, that truck driver wasn’t much of a man, was he?” The waitress said: “No. and he’s not much of a driver either, he just ran over six motorcycles”
