A recent commercial kitchen job resulted in a poor relationship between the 'hood guy' and I. Amazingly enough, after the inspection, the hood lights stopped working.

I found the wires had been disconnected .... presumably in spite, by the other guy. Everyone believed me when I said this had happened.

Why? Simply because I have never been shy about accepting my mistakes. Loose wire nut, oversight, whatever .... no effort is spent to create some fancy excuse.

No credibility = no faith = no business.
