I know this is a weird thing to say, but I think my LBS undercharged me for labor on a repair for my bike. I cracked my right shifter on my Rival and needed it replaced. The part was very appropriately priced (the same as if I had bought it myself on the interwebs-but I only paid for one, instead of the set), but he only charged me $25 labor. I did not complain, but how can a shop stay open, charging that little?
Obviously I will keep using him (I actually bought a new pair of gloves which I could have gotten cheaper at Performance), especially since he was fast and does good work. Can any wrenches comment?
