My father had the spirit and integrity of a scientist, but he was a salesman.
I remember asking him the question "How can a man of integrity be a salesman?"

He said to me, "Frankly, many salesmen in the business are not
straightforward -- they think it's a better way to sell. But I've tried being
straightforward, and I find it has its advantages. In fact, I wouldn't do it
any other way. If the customer thinks at all, he'll realize he has had some
bad experience with another salesman, but hasn't had that kind of experience
with you. So in the end, several customers will stay with you for a long time
and appreciate it."
