I brought my bike in for a tune-up after my fiance had hers done a week before. When I went to pick up the bike the back brake locked up when I went to pay at the counter. The derailleur, the front brake pads, and the back brake, were all worse then before the tune-up and the tire was out of true. Someone took the bike for a "test drive" crashed it and then tried to pass it off as if it never happened. Not only was it out of tune but there was body damage to the bike. I spoke with Nathan the owner, he repaired the bike, did not replace any of the damaged parts. He refused to take any responsibility for any of his employees. When he dropped off the bike a couple days later I spoke to him about an employee almost running over my fiance in the parking lot. His employee was riding a "girls beach comber" bike at high speeds and jumped a curb in front of the store, anyone walking by would of been seriously hurt. Not to mention would you want your daughters bikes mechanical integrity put at risk? He responded "this is a bike shop we like to ride bikes, what do you want from me?"
Cons: I don't have the time to list them all.
