Never Again,
I brought my Mountain Bike in (which I bought 1 week earlier from Walmart) to have them replace my flat inner tubes with puncture resistant tubes.)  I came back 20 minutes later when they said it would be done and as I rode away, the back tire rhythmically rubbed against the back brake.  When I returned and told them about it, I was told the back wheel was not true.  It was true for the whole short week since I purchased it from Walmart.  I plan to take it to their competitor (Landis) and pay the extra $15-$25) to have the wheel put back to the straight condition it was in when I brought it to Slippery Pig in the first place.   I would never give a shop another penny for an extra service I should never have needed on a brand new bike which coasted perfectly when I brought it in.
