+1 on "Find a better shop" My view is that any bike in a shop should be welcomed.
A LBS is into fat tired bikes and every thing else isn't worth their time....so as a result, I went elsewhere. The new shop is terrific. Also, I work on my bike with their encouragement. I know I can bring it in if I'm over my head. And they will tell me how to do it. I think they appreciate the effort (and I buy everything through them). And they are happy to do the work if I need it.
