Let me relate a story. Years ago I worked for a man who owned a business and he was a straight shooter. We had a difficult customer who I tried to deal with and finally washed my hands of her. He called me to his office and said "Confusedjw, do me a favor and drive out to her house and do what you can to resolve this, one more time. Then come see me when you get back." I did and then came to his office. He called the lady with me there. Thanked her for the previous business and then requested that the woman choose his competitors in the future.
He looked at me and said "I don't need every customer."
