Two points:
If I were the seller, I'd prefer to not do business with you because of your track record. I could see, though, the logic in insisting that you pay Friends & Family as a Gift so as to give you no recourse, again, because of your track record.
With all of that said, if the seller of the Mezz cue didn't disclose the warp in the butt and based on the video you posted, it does appear to be warped, then you def should request that he either take it back or make a concession. The other option is that you're happy with the cue as it is and will keep it.
Justin, admittedly, I'm not fond of how you conduct your business but I would not be pleased to receive that Mezz cue myself if it were not described as having that problem.
At the very least you should post a transaction report on OBM on how this cue arrived if the seller doesn't make it right.
all imo, of course.
best,
