Poor Tipper

One day a bachelor who was a poor tipper walked into his favourite restaurant and ordered lunch. A new waitress served his meal and received a three-cent tip. When he came in the next day, she thanked him for his “generosity”, and she said she could tell the character of a diner by the way he tipped.

“Well, what could you tell me about me?”, he asked.

“You put three pennies in a neat row,” said the waitress, and that shows you’re a very tidy person. The first penny tells me you’re frugal, and the second tells me you’re a bachelor.”

“That’s true,” he agreed. But what does the third penny tell you?’

“The third penny tells me your father was a bachelor too.”
