Pizza runs at the schooly-mally place

Another dream involved several people trying to do pizza runs inside some huge school/mall-like building. The first time through, as everyone was getting towards the end of their runs, several things had gone wrong, and some people didn't have their goods to be delivered. I somehow went back to the beginning (i.e. back in time) and assisted various deliverers in getting their stuff. Two blonde girls in yellow fast-foodish uniforms were waiting outside a closed classroom door, but were afraid to knock and ask whether the teacher had the pizzas ready to be collected. So I barged in and asked the teacher, who was in the middle of a lesson. She said the pizzas weren't ready yet. Oops. Closed the door, gave the girls a shrug, went on to another classroom.

This classroom's teacher (reminded me of Nora England) was waiting on somebody to deliver the pizza to her classroom. Just after I inquired about it, a grungy-looking delivery guy came in with a box of sicilian-cut pizza. For some reason, he was writing down the teacher's name on a check while simultaneously slicing and dishing up pieces. Because his hands were busy, he could only write two little scratchy lines on the check where the name should be. The teacher remarked how the pizza was cut so neatly, it was the best she had ever seen. The delivery guy was using a knife and putting a huge amount of force down to make very straight, very deep cuts between the slices.
