I have little patience for the hard sell, no matter what they are selling.

I have actually only wheeled my bikes into shops twice in recent history, and both shops sold lots of used stuff. I do all my own work and wouldn't want to pay their labor rates or live with a result I did not like.

It is fun acting ignorant and seeing if they give you the correct story, though. I have done that lots of times with other items such as electronics. Sometimes you get really amusing answers (lies).

My most recent favorite involved a car rental guy trying to tell me that if I did not take their insurance, and the car was damaged it would be on my driving record! I looked at him with stupefied disbelief, regained my composure, and told him firmly "NO". I should have asked him if I totaled the car, and I bought the insurance, my driving record would be clean?
