I'm primarily a shopper of the bike department, and have unfortunately had negative experiences more often than not. The salespeople are often not very knowledgeable, and while the mechanics usually know a lot - they generally refuse to help you without making you cough up the $$. Tighten a bolt? $5. Use their wrench? No dice. I've developed knee issues due to their poor fittings, and have gotten intense judgement when I need to return items. It hasn't always been this way, but I don't feel welcome here.
