It's nice to highlight the positive stories, and here's one from Consumerist about Chris, a guy whose pizza order got messed up:
After the local store manager insisted that the error was Chris's fault, he fired off a quick complaint on the website. And that's when corporate solicitousness and free pizzas rained down upon him. Not literally. That would be kind of scary.
So Chris got twenty bucks or so worth of free pizzas, and Papa John's got a nice bit of free national publicity. Not a bad trade, I reckon.
