Agree on this. The best away police I've ever known were the Japanese when watching England V Argentina. The police stayed quiet and out of sight in the main. We all knew they were there though in huge numbers but by that knowledge and them not antagonising anyone there was no trouble at all...
On the printing
Surely black and White would work - the bar code is only black and white?
Also the tickets download in a pdf that automatically prints in landscape and you have to physically change it to portrait - that doesn't seem right?
