Well Vegas,
It is in thier own interest.
They sold me my used road bike.
In fact they've sold me almost everything I bought since I started riding, which is admittedly not a lot of stuff.
They do see me getting more and more addicted. They are kind of acting like the proverbial "crack dealer". You know, "here you go, that'll fix you up nice. No, no, this one's on me...".
They see me drooling on the pretty Pinarellos, Fujis and Merlins on the rack and they know if they treat me right, they stand to make quite a few bucks off of me.
Like I said, "you rub myback, I'll rub yours". Fine by me.
