Since Dominos improved, Papa Johns is the worst national brand. I would never sign up for their rewards program and could care less. I actually laughed during the Entertainment Tonight thing or whatever that was when he pitched the deal and mentioned the club membership thing. "NO THANKS!"
FWIW, when I say that they are the worst national brand and I put them behind even Little Ceasars, I am comparing it to fresh pizzas on a good day (too much variance) and not the "Hot and Ready [and old]" ones.
