Thanks all - I'll take the good advice and give them the benefit of the doubt and update with whatever happens today.

Ridebikeme - I had the bike special ordered and they built it up for me, so I don't think anyone would have test ridden it since I didn't buy it off the floor. I definitely had every intention of going to them for the adjustments - I just wanted to have to the LBS near me look at it and make sure it was safe to ride there (I'm still pretty new at this and maybe a little overly cautious)! I do want to have a good relationship with the shop, like you said

Dogmama - I am so sorry about all the trouble you've had. I hope your new LBS treats you better! What a nightmare.
