We have a local "chain" that consists of three shops and is pretty much the only game in town for getting a Trek: Cyclery USA. They tout themselves as "The largest Trek and Specialized dealer in the Inland Empire." With the almost-famous behavior of Trek and Spesh when it comes to dealer agreements, the attitudes of the employees and the overall vibe of the closest Cyclery USA (the only one I've been to) is unsurprising. I don't like 'em. They act like salesmen. Got a flat tire or a wheel out of true? Maybe you need a new bike.
I can't speak for other Trek stores, but the ones around me don't fit my vibe. I can feel the attitude walking in the door. They also pay their mechanics by the piece-- so when you drop a bike off for service, the work will be done with the greatest emphasis on speed, and nothing else.
