When The Doctor picks up the skull he holds it with one hand on the base and the other on the top but in the next shot he is holding it with both hands on the sides.
The Doctor's double portion is served on a single plate at a single place-setting.
The skull that the Doctor picks up is obviously fake, as it has smooth unbroken eye sockets - a real skull would have openings in the sockets for the optic nerve.
The doctor is given two portions of food but only one badge.
