I went to the Cingular store and met David, the representative. My brother and I were his audience. We came to look at options for a family plan in hopes of saving money. My sister, Chantal, also potentially wants to be included on this plan if it will save her money.

So his Watco question was "What are the consequences of switching from single plans to family plans on saving money for Chantal, Vincent, and Ginette?" His enthymeme was, "Switching to a family plan will reduce Chantal, Vincent, and Ginette's individual monthly bills because switching to a family plan will decrease the cost of their overall bill."

The implicit assumption is, "Whatever will decrease the cost of the overall bill will also reduce Chantal, Vincent, and Ginette's individual monthly bills." This assumption is solid because it is indisputable; the audience would completely agree with the assumption.

For David to build clout in our eyes, he told us how long he had worked for the company and proved his claim by being able to answer our random and extremely specific questions. David walked us through everything logically to show us what a great choice it would be to upgrade to a family plan. He did not at anytime try to draw on our emotions; he knew his audience well.

David's argument offered sufficient evidence to support his claim. After calculating out the highest possible monthly bill and dividing the bill in thirds, he showed us that we would be paying less on our monthly bill than we are paying now if we were to buy a family plan. David's argument was typical; he showed us step-by-step how this decision makes sense according to our objectives. We can't tell if David's argument is accurate yet because it needs to be tested to know if it would prove to be true, but the facts seem to indicate that he is accurate. David's argument was relevant; he didn't try to sell us on anything that had no relevance to the situation. He saw our needs and concerns and addressed those directly without trying to make us do something we didn't want to do. David gets an A from me for being an excellent persuader.
