The go to reaction is to complain about how bad his diet must be. It's obviously not the best diet, but I doubt it's any different than what a lot of office workers grabbing their meals in food courts end up having, and it's a lot cheaper. The real problem is its only feasible if you live right by the Six Flags, which is I suspect why they can offer this.
It reminds me of the story of the guy who bought a refundable business class plane ticket so he could eat all his meals in the lounge and kept changing the ticket. He was caught eventually though.
