well congrats on getting the new bow home, but sorry to say it sounds like that bow shop is mostly worried about the sale and not service
all bows are set to "X" set ups at the factory
and are set by humans, humans have bad days, lazy moments, and some just don't care how one leaves a factory
a GOOD bow shop, shoukd notice thing out of norm
and be more than willing to make sure the bow is set up, you happy before you leave there shop with it
but like i said before, so many folks today don't care or know what to look for, or are just happy with a new bow, no matter how its set up, lots of weekend warrior hunters that OK is all they care about, not a in tune set up right bow needed for so many!
i would paper test it now, and see if further tweeking is needed
good luck
