15+ minutes of gameplay is going to be you walking from the kitchen to the delivery window and then back to call the customer for the order
And that's not accounting for players not getting things prepared by having all their ingredients nearby or the time it takes for you to run around the kitchen.
There's also some pizza that was already prepared that I didn't see. I don't like all of these back and fort walks, but this is also the first game I had played in this style. Not a fan. I would had liked the game more if the place was smaller and you could call for the customer in the delivery window instead of the kitchen
