Years ago Patrick J. O'Haire Joined one of my classes.He had little education, and how he loved a scrap！He had once been a chauffeur, and he came to me because he had been trying, without much success, to sell trucks.A little questioning brought out the fact that he was continually scrapping with and antagonizings the very people he was trying to do business with, if a prospect said anything derogatory about the trucks he was selling, Pat saw red and was right at the customer's throat.Pat won a lot of arguments in those days.As he said to me afterward，"I often walked out of an office saying：'I told that bird something.'Sure I had told him something, but I hadn't sold him anything."
My first problem was not to teach Patrick J. O'Haire to talk.My immediate task was to train him to refrain from talking and to avoid verbal fights.
Mr. O'Haire became one of the star salesmen for the White Motor Company in New York.
How did he do it？Here is his story in his own words："If I walk into a buyer's office now and he says：'What？A White truck？They're no good！I wouldn't take one if you gave it to me. I'm going to buy the Whose-It truck.'I say，'The Whose-It is a good truck.If you buy the Whose-It, you'll never make a mistake.The Whose-Its are made by a fine company and sold by good people.'
"He is speechless then. There is no room for an argument.If he says the Whose-It is best and I say sure it is, he has to stop.He can't keep on all afternoon saying，'It's the best'when I'm agreeing with him.We then get off the subject of Whose-It and I begin to talk about the good points of the White truck.
"There was a time when a remark like his first one would have made me see scarlet and red and orange. I would start arguing against the Whose-It；and the more I argued against it, the more my prospect argued in favor of it；and the more he argued, the more he sold himself on my competitor's product.
