I brought my wife's 1989 schwinn into a shop for a tuneup/rehab when we moved to town 11 yrs ago and they refused, said we should just buy another bike and they were having a sale in another 2 weeks. I haven't bought anything there since.

The next shop I took it to did a great job of rehabbing the schwinn and I was so happy with that that I stuck with them despite two severe problems over the next couple years. I still valued that shop for conversation just not for buying stuff. So I was a pretty awkward customer there I guess. They closed recently.

In fairness, the first shop I went to was probably assuming I wouldn't pay $200 for the rehab of that bike, but I did (to another shop). At a 3rd shop, I saw lots of people freak out at realizing they wanted more than just a bike (raincoat, rack, panniers...) and walk out when they saw the other stuff would cost the same as the bike they wanted. That shop is gone now too.
