I had several experiences last summer with the WAM service department and delt directly with their service manager. He made my service experience very comfortable and was very professional. As a business man, there are some relationships that just do not make good business sense. This would appear to be the case. WAM is a business and most likely replaced AMeckler with someone like myself that would embrace all their services.
I would argue that AMeckler was given ample time to find a new location which he did. Sounds like it was a win win situation for both parties involved. As for the WAM service manager being rude I find that highly doubtful. Perhaps he was surprised to see your wife at the service shop knowing you perfer to have your boat worked on by Silver Sands. Perhaps next time call them when you break down.
