I mean, Chuckies pizza is slightly better than Domino’s pre-recipe change, and that went on for decades. It’s not like there’s a high bar for selling pizza. You can sell a stale cracker, with tomato sauce on it, for a long time before going bankrupt. If the crackers are cheap enough.
Also my bet is that it was just a way for them to keep some revenue flowing, keep people employed, and not have to shutter their entire business. I mean lets face it, their business model is spreading diseases while, entertaining children whose parents are ordering beer by the pitcher. Not exactly a winning model during a pandemic. They had to do something.
