So here's how it works: When I worked for Dominos Pizza I did delivery, which was my primary job. But if you came back to the shop from a delivery and there weren't any new deliveries on the shelf ready to go, you took orders and made pizzas. Nobody ran to the restroom and washed their hands. You just grabbed-up a ball of dough and started shaping it onto a flat, round circle making sure not to tear it. If you wanted to be silly, you could spin it and toss it into the air, which was a really good way to tear the dough, so they recommended you not do it that way. You laid it out on the counter and punched it and pulled it and used your thumbs to shape the outer lip. But you handled it with your bare hands. That would take two or three minutes. If everything looked good, untorn, level and smooth, well-shaped and not lumpy, then you carefully picked it up and placed it onto a screen that would carry it through the oven.
Then you grabbed the ladle and put tomato paste and spread it around until it covered the dough, except for the outer lip (it doesn't look good if you spill tomato paste on the lip - you want a clean crust). Then you pushed it down the line and either someone else would take care of loaded stuff on top of it. Almost always it started with Mozzarella cheese and pepperoni. Then other stuff, according to the order.
We had pineapple too, and I personally believe that pineapple on pizza is a sin, but some people wanted it.
After that, you didn't touch the pizza again. You placed at one end of the oven on a conveyor and it went very slowly through the oven. At the end of the oven, the pizza has a temperature of around 600F, so you have to use a large spatula to move it from the end f the conveyor to a table where you identify what type of pizza it is, then find the box for it (there might one box or fifty on the top shelf of the table, so you had to keep track), then use the spatula to place the pizza in the box. A round cutter was used to slice the pizza quickly into eight pieces. You did this quickly, because while you're doing that, more pizzas are coming out of the oven. During very heavy periods, two of three guys worked a the end of the oven.
Very often, if you were a driver, you might box and cut the very order(s) you were going to deliver, sometimes three to five deliveries at a time. You grabbed up your order(s), ran out the door and loaded up your car, and then you were off!
Every bit of the food was handled by hand. You made the crust by hand. You put the cheese on by hand. The pepperoni was placed carefully and evenly by hand. We had ham, bacon, pineapple, sardines, and now I can't remember all of the other add-ons, were all placed by hand. And after you did that, if you weren't on your way out the door, you either went over the make another pizza or to the end of the oven to box and cut them. Or to the phones to take more orders.
You drove out across town or whatever address it was, made your delivery and then back to the shop to do it all over again.
I used to keep track of my delivery times, and the fastest order I ever delivered was around two or three minutes, which was a record (for me). It was to a hotel, practically across the street, while I was taking the order, the manager looked at my screen and made the pizza, by the time I got the address and off the phone, the pizza was coming out of the oven, I grabbed it, boxed and cut it, ran out the door and delivered it. I wish I could remember the exact number, but it was so fast that it surprised the customer.
