I go to my LBS and my lawn mower store for service after the sale. Like loading my weed eater with string, or repairing a pinch flat while I wait, or making an adjustment to my chain saw.
True these are all things I could learn to do, but so far I have not and appreciate people that can do them. Dropped my bike off Saturday morning for new brake pads and brake adjustment, then picked it up in the afternoon. Can't imagine Wal-Mart being able to compete with that.
