You'd forgive the bus company for not being aware of the march, it has only occurred 8/9 times. The Nix have played more times in Auckland than AFC have.
I'd say that this was a police / AFCBK problem. Not the bus company, who have probably driven the same route regardless of who is playing there. If there was a march, AFCBK should have made that known to security and the bus company. I'd imagine it was a convenient inconvenience. Petty.
