A young man just got a new job running the register at a store. The old-timer said he would teach him how to sell things. "Watch how I do it" he said to the new hire as a man came up to the counter.
The customer put a bag of grass seed on the counter. The old-timer then said to him "You know when you plant those seeds and the grass starts growing you're going to need a new lawnmower to cut that grass." "You know," said the man, "I do need to get a new mower, sure I'll take one."
After the customer left, the new kid said, "I think I see what you mean. Let me handle this next one." A man then stepped up to the counter and set down a box of tampons. The young salesman then said, "You know you should get you a new lawnmower to go with that."
The man then asked the young salesman, "What are you talking about?" "Well," he said, "It looks like your weekend's shot so you might as well cut the grass!"
