Definately, if they didn't test ride it, they didn't do their job.
I would understand if it was lever or twist shifters, but this is a new roadbike, which has neither of those, so there is no excuse for that kind of maladjustment. Test rides on any cable adjustment, especially derailers should be done religiously. It annoys me to no end seeing folks not used to working on bikes adjusting brakes and thinking it works right without an actual test. My test for my mtn bike is I find a way to put all my weight in a 45 degree angle to the wheel while the brake is engaged...if it makes ANY movement...then it's maladjusted. That works fine for brakes, but for derailers the only way to be sure is to actually ride it, no exceptions.
