The funny thing isn't that some LBSs don't have racks--it's that almost none of them do have racks.
The owner of my LBS said they don't need a rack because very few customers actually ride a bike to the shop. 99 % drive there! Fewer people ride to a bike shop than ride to the average coffee shop.
The owner also told me that they don't need a rack because they have no problem with people bringing bikes into the shop, even though it's small and crowded.
One time we had a little fun with them. I was on a ride with three friends and I wanted to pick up an inner tube. Nobody wanted to stay outside to guard the bikes, so I said, "We'll all go in--he told me it's OK." They sure freaked when all four of us walked in with our bikes!
