Now I know who this is. There is only one possible neo who could have thought I was a plumber.
While I was not a plumber, several years ago I did have a chemical supply company and one of my customers was RMS. Part of the service was maintaing the dispensers which were hooked up to the kitchen plumbing.
A person not really knowing my business but knowing that I was the person to call when something needed tending to in the kitchen would have thought of me as a plumber. And she was the one who always called me to come and fix a problem.
This would also comport with "Diana's" obvious difficulty with wording things, being ESL. Don't worry, mam. It will be our little secret. I just feel sorry for you.
