Pizza Hut's AI system caused 'cascading' problems and $100M in damages, franchisee alleges in new suit

I pretty much boycotted subway over this but ate there a lot before Quiznos and would always get my sub toasted. They might have upgraded the ovens/toasters, though.
I think they are faster, like they used to have enough time to build a friend's sub while the first sub was toasting but now they don't.
