The bike shop I frequent most often is about 5 blocks from my house. I ride my bike directly into the store, whether I'm having it worked on or not. Often, I'm just buying a small part, or asking a wrench a question. The store itself is clean and neat. While I'm in there, I see many other people also bringing their bikes in. The floors are completely spic n' span.
Just Saturday, my husband and I rode our bikes there, and propped them up against a post in the store. Then we were able to look at grocery panniers and determine which ones would not interfere with the brakes on his 1984 Trek 720. I picked out another headlight, installed it right there, and then we paid for the bag and the light. The sales staff were friendly and helpful. The owner asked me if I ever found the Terry I wanted, and then ooohed and aaahed over my bike, which I hadn't bought from him.
Anyway, it's a great store. All the other bike shops in town are like that, as far as I can tell, even the teeny ones. I wouldn't shop at any LBS that treated my bike like something dirty.
