A sale representative stops at a small manufacturing plant in the Midwest.
He presents a box of cigars to the manager as a gift. "No, thanks," says
the plant manager. "I tried smoking a cigar once and I didn't like it."

The sales rep shows his display case and then, hoping to clinch a sale,
offers to take the manger out for martinis. "No, thanks," the plant
manager replies. "I tried alcohol once, but didn't like it."

Then the salesman glances out the officer window and sees a golf course.
"I suppose you play golf," says the salesman. "I'd like to invite you to
be a guest at my club."

"No, thanks," the manager says. "I played golf once, but I didn't like
it." Just then a young man enters the office. "Let me introduce my son,
Bill," says the plant manager.

"Let me guess," the salesman replies. "An only child?"
