How to lose a sure-thing sale

1) Be a snot-nosed know-it-all kid.

2) Never make eye contact.

3) When your customer says, "We'll take this one," shrug your shoulders and say something like, "Well, okay."

4) Proceed to try to sell your customer "fries" with their "order". Especially after they tell you, "No, thank you. We just want that."

4) Once you have the keys to the cabinet that holds the high-ticket item your customers are trying to buy, start a new sales pitch with the next couple and make the first couple wait. Because you know they can't get the thing themselves.

5) Wonder why we walked away without buying a damned thing.
