I brought my bike on vacation for about a week this summer and realized almost immediately that I hadn't tightened the headset enough and it was coming loose. I took it to a local bike shop and told the obviously high kid in there the problem. He told me no problem and proceeded tighten the top nut as tight as he could with a big crescent wrench even though I could see the correct tools hanging on the wall feet away. He rolled it back and, as you'd expect, the headset hardly moved. I asked him if I could do it really quick and basically taught him how to adjust a threaded headset. I guess they only really deal with garbage beach cruisers and threadless headsets.
I came back the next day and talked to the owner. Apparently the kid was his nephew and basically a warm body there to inflate tires and other little things during the busy season. He then showed me his NOS 531 Team Raleigh the hes getting ready to sell for +$2500 and let me peruse his two storage containers full of bikes.
