My LBS is too small to carry a lot of stuff in-stock. There just isn't room in the store.
But, several of the staff commute and that's important. They understand the differences in the way commuters ride as opposed to racerboys.
Most importantly, there's a separate service bay for ride-ins, with car-free and commuters getting priority. I like it that when I ride in, instead of being asked, "When can you pick it up?", I'm asked, "Can you wait a minute until I finish putting new brake pads of this bike?"
