That was pizza!
We have all kinda accepted the fact that sometimes our packages will arrive a little banged up because the delivery guys throw them a lot. But it would take a long time for people to get used to the idea of their pizza boxes being tossed at their doorsteps.
When your pizza is at stake the delivery people should not make such moves, especially when they can simply knock on the door like normal human beings. We can imagine the frustration and betrayal the pizza recipient must have felt having to eat a delicious pizza in a bad shape.
