New Sales Assistant

A new sales assistant was hired at a large department store. On his first day, the sales manager took him around to show him the ropes. They were passing by the gardening section, when they heard a customer asking for grass seed. The sales manager stepped in.
Sales manager: Excuse me, but will you be needing a hose to water your lawn?
Customer: I guess so. I’ll take one.
Sales manager: And how about some fertilizer and weed-killer?
Customer: Um, okay.
Sales manager: Here’s a couple of bags. You’ll also need a lawn mower to cut the grass when it starts growing too long.
Customer: I’ll take one of those too.
After the customer left, the sales manager turned to the assistant. “You see?” he said, “that’s the way to make a good sale. Always sell more than what the customer originally came in for.”
Impressed, the assistant headed off for the pharmaceutical section, where he was to work. Soon, a man strolled in.
Man: I’d like to buy a pack of Tampax, please.
Sales assistant: Sure, and would you like to buy a lawn mower too?
Man: Why would I want to do that?
Sales assistant: Well, your weekend’s shot to hell anyway, so you might as well mow the lawn.
