I buy my LBS stuff from a shop in Poway, and they have always treated me fairly. I don't buy much, usually spokes and tires. There is one employee there who I have given the link to this board to. He knows all about my Paramounts but I have yet to bring one in the shop.
I tend just ask for the specific item I need and not distract them with other stuff. One other large LBS has been rude to me and referred to me as "the old Campy guy", though not in a particularly friendly manner.
I also go to a couple of other small shops that are C & V friendly. I like those stores!
