Quality/Convenience
Where are you located?
I have two shops which take great care of me but some of that is because I have built up good relationships with them over the years, enjoy the staff and ownership, and have had a presence in the local MTB High School League for the last 2 years. They are also the two closest shops to my house. As you can see these qualities have not mentioned any wrenching and may not work for someone who just walks in the door and expects the world. I know arider who doesn't like the "vibe" in one of the shops and prefers the other; the "other is just down the hill from his house and he has gone there since he started as a BMX kid.
