This story reinforces two of Carnegie’s key ideas. It was crucial that Detmer acted both positively and selflessly in this meeting with his customer. Rather than take an argumentative approach, he showed that he actually cared about the customer’s needs and input—being willing to wipe the charge, thanking him for alerting him to the mistake, and offering to find him another company. Only in taking this selfless approach was Detmer able to keep the customer’s business—and the customer later admitted he was wrong and paid the charge anyway. This shows how those who act selflessly are more likely to get what they want.
