The other LBS are more understanding of the fact that I shop around for the best fit. The Trek guy makes it sounds like "we can just change the Madone to your preferred fit"...
To some degree, yes. A new stem, a seatpost with a different setback, and a variety of other tweaks can make a difference. How much of a difference it makes depends.
