Some shops are like that, sadly.
Oddly enough the shop I didn't like here has started to become one of my favorites...turns out what happened was the owner did make a big mistake and doubted my abilities....turns out he saw me at one of the local club rides (I'm not fast, but I'm no slouch either), and he realized I do know what I'm talking about...
...since then he's been giving me pretty good advice, and it looks like he's starting to get used to the fast utility cyclist crowd a bit more.
Maybe that's his thing....he probably doesn't know enough about that bike.
