Could be rough, but if they are good and customer friendly I think they do well. I am lucky to have a pretty awesome LBS in my town. It sells Trek exclusively, but the draw is their customer interaction and service. There are people that come from a few hours away, passing many other bike shops, just to get their bikes worked on.
Now they also do something that is a little unusual. If you buy a new bike from them you get lifetime maintenance/adjustments for free (you do have to pay for any parts of course).
