I'm pretty anti Dave Portnoy overall, so don't mistake this for being an apologist, but that's not really what happened. He gave it a pretty mediocre review (and has acknowledged he doesn't like to go super harsh as he knows it can fuck with peoples' businesses), and the Dragon guy stormed outside without even knowing that and started an argument with him on camera. Portnoy's a piece of shit, and he loses any high ground he has in this argument when he starts yelling about the guy being fat and how rich he is, but he didn't start it and I think just about anyone with a food review video platform is posting a video where the place they're reviewing starts shit on camera mid review.
I've side eyed Dragon ever since the owner posted a receipt with a guy's name, phone number, and address on instagram when he didn't tip enough on a delivery. That said, I don't root for anyone who isn't racist/bigoted/abusive to lose their business, and they do have pretty good pizza, so I hope he can weather the storm.
