As others have made automotive analogies, I'll add mine. When I got out of the service in 1970, I went to work at a small Lincoln and Mercury dealership as a service advisor. We had a wise old salesman who shared that he learned never to judge a customer by appearance, He had an older gentleman cone in, dressed in overalls who wanted to look at cars. Longer story short, when he decided what he wanted, he went and got a paper lunch bag and pulled out a wad of bills and paid cash for a new Lincoln. Turned out he was the owner of a successful steak house.
I carried that thought with me through my career in the business and made it my policy to always under promise and over deliver, In later years, when I spent a lot of time in wholesale parts, I had a lot of customers who would always ask for me when putting in their body shop orders,
