In my view, Bike Jambalaya is partly right. Go into the LBS at 5pm on a random Friday night in the middle of winter, and you will likely be called by your first name, as you get the shop's full attention and immediate service, as well as all the local bike scene news. Go into the same shop at noon on a Saturday in May, and you might wait in line to drop off your whole bike to a pimply teenager behind the counter.
Part of being a really good customer is knowing and respecting that difference.
