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 with a bitter smile: "An only child?"
