A fecal is definitely in order.
It's not eating and has one eye smaller than the other.
It may have hidden problems as well.
I would be at the vet immediately if I opened the tub and saw a pile of green crap in there. That's not normal.
Out of curiosity, was this spider priced at typical retail or did the seller give a steep discount.
I would think it would be heavily discounted since it can never be used as a breeder.
Your friend needs to get a fecal to the vet asap and whether or not the person likes it, you need to make people aware of someone selling defective spiders without disclosing the information on it.

BTW, a $20 fecal is nothing compared to what it may cost if there is a problem and it gets worse.
