I think I figured it out. Truet Cathy is a lich. It's the only reason for people to like Chik-fil-A as they do. I believe as a 20th level divine cleric Cathy cast a permanent geas spell on his chicken. I also believe his phylactery is the Peach Bowl trophy. Some time in his service to the holy bovine he achieved lichdom.
I made my save against his spell years ago. Those that fail to eat his cursed chicken at least once a week are doomed to become chickens and thus a part of the perpetual spell. I still don't know how his victims survived Christmas. All restaurants were closed on Sunday. Christmas Eve closed at 6pm and all day Christmas.
I'm just continually amazed at how busy they are. To me the sandwiches are average. No better or worse than others. I get chicken sandwiches at Burger King when I can. Just as tasty and often cheaper. Also available when I want them since some BKs are 24 hours.
