Hmmm... 3 euros isn't too bad for a tuneup. I have to say, we have the best mechanics here in Austin, Texas. I usually work on my bike myself, and if I do take it in, it's because something stumps me or I don't have the right tools for the job. Luckily the bike mechanics will usually do what I want for free though I don't expect them too and give me some tips for working on my bicycle, I'll usually buy something from their shop or bring them some referral business in return.

Good luck, remember that customers that expect everything for free this very instant, exist in every market, the trick is to just say NO.
