I thought that was kind of obvious.

A friend of mine who repairs PCs occasionally finds nothing wrong with them and does the usual "I'll run some maintenance on it" and the client is always happier afterwards. He doesn't charge for stuff unless anything needs to be done.

Wouldn't your friend get happier clients if he charged them a little bit? It'd probably give them a stronger placebo effect.

People are shallow. The computer is their best friend 95% of the time, but they remember the last 5% and how much it cost them more than anything.
