Three Hell's Angels were in a greasy spoon when they noticed that the only other customer was an old bloke sat on his own. They went over to his table in threatening mode, and one of them spat in the old boy's coffee, one poured a load of salt all over his breakfast and one put out his cigarette in his fried egg.

The chap got up without a murmur, paid his bill and left.

"Not much of a man, was he?" sneered one of the greasers.

"Not much of a truck driver either," said the waiter looking out of the window. "He's just reversed over three motor bikes."
