I don't have the tools, space or knowledge yet to do much of my own bike maintenance so this will probably be a dumb question--so be it.
Should a freshly cleaned and lubed chain (allegedly done by my lbs as part of their "Basic Tune Up") still be covered with the same black gunk that I got all over my hands when I fixed the rear flat tire a few days ago? It doesn't appear to me that anything was done in the way of cleaning or lubing (the rear derailler also appears to be as dirty as it was before), but I'd just like to know before I take it back and complain.
How can I be sure that the shop has really done all the work they charged me for? If I knew enough to do it all myself, I'd know, obviously, but then I wouldn't need the bike shop; eventually I will, but for now I need to be able to trust the people I'm paying to maintain my bike. Advice?
