The Trek store will likely do the fitting but may charge. I had my road bike re-fit at a Trek/Specialized exclusive store. They had no problem fitting my Cannondale and never treated me poorly when I brought it for service. In fact that is how they won me as a loyal customer. They also are patient with my personality, teach me to do things if I request so and will do many minor repairs for free (long before I bought a bike there). DH and I now have bought two bikes each from them and race for them. I have referred many newbies to them, even my CFO who wanted to get an old bike his daughter had for college tuned up. He said they treated him like he had a top of the line bike.
And that is how you do customer service! So no you don't expect too much. Everyone should be treated like they are important because they are. Their feelings should listened to no matter how silly they sound to the fitter or customer service person. If they handle everyone like you I am not sure how they stay open!
