Dad's version
A question of logic for you. You get isolated from your dad in a large crowd moving in both directions after the RWC final. You know most people are heading for train and that trains are only travelling back into town directly to the stop where the boat is moored.

Do you stick with the crowd and hook up with your dad at VIP entrance to dock where there are lots of security guards and it is less crowded or do you immediately speak to a policeman once you are isolated in the crowd (bearing in mind done this 3 times and crowd very friendly)?

Well Callum took the police option which meant instead of getting to boat at midnight, it was gone 3am.
