I definitely think there should be a form of survival mode with the cooking (i.e. one round you have to cook a certain amount of hot dogs and burgers and the next round increases the amount, etc) but there could be the addition of maintenance going on, like the cooker blows up and you have to play a mini-game to fix it, or the fuse goes and everything stops until you get the fuses done, or various phonecalls come through saying that a last minute delivery has been ordered and the Kiosk guy has to prep something alongside other orders. And then of course you can have smokey ghost appearances too...
