Tulip, given that the shop is in Concord and you know the peculiarities of New England small towns, the fact that he is a doctor at the local hospital up the street probably just comes up in conversation. This is the shop where I had an experience very much like Catriona's. I bought a bike that really did not fit me and they tried to convince me otherwise. When I researched and came armed with information, they got a little nervous because i constantly kept coming back, alone, with my DH, and once with my exchange student son who was a pro at the time... they realized that every time I was in the shop I knew someone else in there; not only people from Concord and the 2 other surrounding towns that I lived in, but I actually knew a lot of the local racers from when my son raced in high school. So, they were "happy" to exhange my frame for one that fit, but I had to do the research for the narrow, short/shallow bars, R700 shifters and tell them to put them on my new frame (and I paid for those). I am happy with my bike now, but the process took two years!
The last time I was in there, the owner noticed me talking to yet another racer I knew, and my DH leaned over and said to him, "You know, she knows everyone in Concord, Acton, and Boxborough, so...."
