I think you did right for walking, and for not posting the shop name here. I think that in spite of the fact we are enthusiasts, we should expect quality service from the shop we patronize. If we can't get it, we should buy elsewhere, and/or train ourselves to service our bikes.

By the way, I keep all my setup measurements in a small, spiral-bound log in my tool box. These measurements should include correct saddle height from BB ctr., the distance the tip of the saddle is set behind the BB ctr(saddle setback), and the distance from the saddle tip to the ctr of the handlebars. If you know what these should be, you can set up any bike in ~5 minutes to suit you, adjusting for crank length, pedal/cleat differences, and handle bar stem length.

I also record all the frame/fork specifications like fork crown race seat to frt. axle ctr.(in case I want to swap forks), head tube lengths, top tube lengths, angles, etc... for all my frames. How can these be helpful? I have been considering purchasing a Reynolds Ouzo Pro fork for one of my bikes. The fork has a 372mm fork crown race seat-to-frt. axle ctr. dimension. My current fork has a 367mm fork crown race seat-to-frt. axle ctr. dimension. That is .5 centimeters and will change the handling of the bike. Good to know.
