The pizza from most chains (Dominos, Pizza Hut, Papa John's, etc.) is cooked on conveyor belt ovens. Most of the time the pizza comes out undone.
The only way to cook a pizza is in an old style pizza oven.
As for the help in these places, it's symptom of a good economy and the state of public education.
Do you remember the stone oven baked pizzas from Shakey's back in the late 60's and early 70's?
Pizza crust to die for....
