I would take it back and have them check it out, but if you can't do that, it's probably pretty safe to just hand tighten the screws in...
Most techs are usually pretty good at always checking to make sure the bindings are on flush, but sometimes, especially during the holidays - or those in their first year - just totally derp. I'll honestly say I've done it before and felt like a total idiot. it's a pretty easy fix however, so you should be okay.
Have a nice day, Bluename.
