Our favorite LBS closed doors a couple of years back. We would stop in during or after rides and hang out with them quite often. I bought more than a few bikes from them over the years and really miss it. At closing time on Fridays, it wasn't unusual to end up there for a couple of cold ones.
I normally do all of my own maintenance and buy parts online but I did have them assemble one bike for me. The mechanic who did the work loved it because it was truly assembling a complete bike. Normally it is pull the bike out of a box, install pedals and handlebars before truing the wheels. I did it because they had housings and cables and in the end made them charge me more than they did.
The other bike shops in the area just aren't as friendly.
ETA... If potential customers stopped in while they were busy on the phone or with other customers, we'd break the ice and chat with them about bikes and what they needed.
