"It's unfortunate that this co-worker Parent didn't come to you before the purchase"
Spot on there. The other unfortunate thing in this is that there are so many "music" shops willing to sell unplayable pieces of c**p (not just guitars)to people and take advantage of the purchasers lack of knowledge. It is a bad business decision by the store, and ends up with people who could be return business thinking "I can't get the hang of this, it's too hard, I won't bother". Shame.
