If you look as if you’ve seen a ghost, you look very frightened or worried. Someone who is witness to a crime sees something happen that is against the law.
A hold-up (US ifml. also: stick-up) is an act of stealing from a bank or a shop, using a gun or a knife.
If you hand over something to someone, you give them something because you are forced to do so.
The takings are the total amount of money that a shop receives from selling things during a certain period of time.
