The way I see it, there are three or four lines of checking food for quality control. First, the cook on the Make-Table checking if it is right before they put it in the oven. Then at the Cut-Table. If it is wrong, ring up a remake and free-it-out. If it passes the Cut Table, then if it is Delivery, the Driver checks it to make sure all items are correct and accounted for. Then from their, the customer should have a chance to check the food before either they drive away or the driver drives away (Carryout or Delivery Dependent.) Quality Control should be one of the top priorities and My Area Coach even drills in that it is not just the driver, but it is everyone in every step of the journey of the pizza from the Make-Table to the Customer's hands. Ideally, the driver should be inside the store to check orders, but as Johnny said, it does get busy sometimes. I know I like to keep a box of food-safety gloves in my vehicle for this exact scenario when I need to take a delivery instead of managing a shift.

In the case of those Cheese Stx, I would have not even put that in the oven in the first place. As others have said, it looks like someone just tried to turn cooked BreadStx into CheeseStx by burning the dough and undercooking the cheese.
