The bike was likely stolen and the guy who had the bike wasn't quite firing on all brain cells. I have no issue with people who want to do the work themselves but they are generally up front about it or will mention it at some point in the conversation and if they are able to work on their bike generally it isn't such horrible shape.

If the bike is unsafe, it is unsafe and if we cannot do the work to make it safe, we aren't going to do the work. What could and most likely will happen is someone will ride and something bad will happen and then they will come and blame us. It is a major liability to send someone on down the road with an unsafe bike especially with the lawsuit crazy culture we have built up.
