The gang of 16 potential apprentices are split into teams for a simple selling exercise.
£600 of fish in a van. Choice of 4 markets in London. One day. Make a profit.

Selling fish should be easy. They're given a book of pictures to ID the fish, a wholesale pricelist and they manage to price really wrongly.
