Ben has nine serving dishes (a stack of 5 and a stack of 4) in the kitchen, and as he enters the rotating door, one of the dishes seems to slip off the stack of 5, which he catches with his forearm. However, when he enters the restaurant, that dish has vanished entirely.
Rona gives her details to the ship's crew carried in the white van. While amusing, it makes no sense as she doesn't own or insure the car, and the crew were not driving the van. In addition, the van seems to have disappeared entirely when the Chevrolet is backed away from the commodore's Mercedes.
