I have been into bikes for nearly 30 years now and in all that time I have only ever found 1 bike shop that isn't up its own arse. Even if I go in an speak in a knowledgeable way about exactly what I want I will nearly always get condescending answers in return. They all act like this clique that you are not a part of and so look down upon you as an inferior.
So your experience doesn't surprise me in the slightest. On forums and the internet in general people bang on about your LBS and supporting your "local bike shop" and all that trash but why would I want to support a bunch of cunts who think they are better than me and actively go out of their way to try and prove that in every interaction.
