There are many arrogant LBS in my area. Some of the store clerks would respond in a attitude that turn off would be customers and new cyclists which is too bad because that $$$ lost.
There is a section in MTBR.com that has LBS ratings by cities. Lately MEC has started selling bicycles and alot of LBS in the vicinity cry foul. I bought my bikes from LBS in the past, I've not returned to that LBS for service since I can get free tune-ups at various bike clinics/events. My next bicycle is likely not from my LBS because due to selection after learning what I know now about bicycles.
