Platform 9 3/4 All for Harry Potter !

As I seem to be meeting friends at Kings Cross station alot recently I had to take a photo of this . Every day there is a long queue of people who want to the hold the luggage trolley , wear the scarf and then leap into the air . The chap on the right holds the scarf and then throws it in the air at the right moment !- It seems to be his job - I have no idea if they pay for this or not?
No white owl was injured in the taking of this blip
