Tried it

A sales representative stops at a small manufacturing plant. He presents a box of cigars to the manager as a gift.

"No, thanks" says the plant manager. "I tried smoking a cigar once, but I didn't like it".

The sales rep shows his display case and then, hoping to clinch a sale, offers to take the manager out for a round of drinks.

"No, thanks" the plant manager replies. "You know, I tried alcohol once, but didn't like it.

Then the salesman glances out the office 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".

"That's kind of you, but 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, Mike" says the plant manager.

"Let me guess" the salesman replies

Spoiler:

"An only child?"
