I could side either way. Yea its bogus for the $10 for something that simple. Then again, the whole idea of doing service work for free get really old FAST! I cant tell you how many people's cars and bikes I have worked on in the past not getting a dime. I was nice and did something as simple as tightening a friends chain. Someone else sees or hears I didnt chrage them, cuz I was being nice, then everyone shit tons of people come out of the wood work wanting it done for free.
