A young man got a new job running the cash register at a general store. The old store owner promised he would teach him how to be a salesman and up-sell. "Watch how I do it," he said to his new hire.
As a customer put a bag of grass seed on the counter, the old-timer said to him, "When you plant those seeds your grass is gonna start growing and you're going to need a new lawnmower to cut it." "You know," said the customer, "I think you're right. I do need a new mower. Sure, I'll take one."
The new kid said, "Wow. I think I see what you mean. Let me try one." The next customer in line stepped up to the counter and set down a box of tampons. The young kid said, "You know, you should get you a new lawnmower to go with that." The man asked the kid, "What the hell are you talking about?"
The wanna-be salesman told him, "It looks like your weekend's shot, so you might as well cut the grass."
