I was in walmart today looking at the bicycles, and some of them are so poorly assembled that I wouldn't let my worst enamy ride them. I had my allen wrenches with me, so I started making some adjustmants on some of the bikes (properly positioning brake levers, tightening brakes, etc.) Suddenly this guy comes up to me and asks me what I'm doing, and I told him. He then tells me that he is the bike assembler, which kind of surprised me because he didn't have a store uniform on. He gives me the blah blah blah about not working on the bikes since I don't work there. I talked to the manager about the unsafe bicycle assembly, though I seriously dought anything will be done. Should I have attempted to make the bikes a little safer by adjusting them, or shoud I have just said to heck with it and hoped for the best for anyone who rides them?
