One mechanic is sitting on the roof of a school bus with an open door, while the other is standing inside the bus.
Two workers are scrapping and old school bus.
We have no idea if the guys are scrapping the bus, they could be doing a number of things. We have no idea if the school bus is old, it could be newer.
