As the OP I ask that this thread be closed. As soon as it drifted into personal attacks the cause was lost. I only wanted a discussion about how to value information that one can't gain on their own. I offered two variations on the shop's actions, neither was done by the shop and not by me at ant shop I've worked/owned. But The question was put out here as an academic exercise. that some seem to not be able to understand critical debate is sad. So, again, can this thread please be closed and locked down. Andy.
