A trainiee shows up for his first day at Wal Mart. His supervisor tells him "Kid, I'm going to teach you the art of suggestive selling." A customer walks in, and the supervisor says "Watch this".
He walks up to the customer and says:

"Good Morning sir, how can I help you"?

"I'm looking for some grass seed."

"Certainly sir. You realize you are going to need some fertilizer with that."

"Why do I need fertilizer?"

"You need to fertilize the seed so it will grow."

"O.K. Give me some fertilizer."

"Certainly sir, you realize you need a garden hose."

"why?"

"If you don't water the seed, the fertilizer will burn it out."

"O.K. Give me a garden hose."

"Certainly. You realize you will also need a lawn mower."

"Why do I need a lawn mower?"

"You're taking such good care of this grass, it's going to grow like crazy. You'll need to mow it."

"OK. Give me a lawn mower.

The supervisor rings up the purchases and returns to the trainiee. "See kid, that's suggestive selling." Another customer comes in. The supervisor says "Give it a shot." The trainiee walks up to the customer and says:

"Good Morning sir, how can I help you?"

Embarrassed, the guy says "I need to pick up a box of tampons."

The trainee responds. "You know you need a lawn mower with that."

The supervisor buries his head in his hands....

"Why do I need a lawn mower?"

"Well, it looks like your weekend is shot, might as well do some yard work."

Thank you, I'll be here all night.
