Maybe all the sports analogies is overdoing it.
But this is basically what I'm thinking:
Those Chicago fans bought a ticket for the Creed concert. They were really only guaranteed a Creed concert, and that's it. There was no guarante that they would hear their favourite songs, that the guys would be playing at their normal high standard, that the sound systems would be working perfectly, that they would even enjoy the show, etc. Keeping in mind, some of those "fans" are enormously disappointed and angry about it, while others were disappointed but are over it.
Same thing goes for my cricket match (
). I bought the ticket, and expected a cricket match, which I got. There was no guarantee that my team would win, that the match would be exciting, that my favourite player would be playing (and if so, that he would be playing up to his normal high standard), etc.
The Chicago fans paid for a Creed concert, and a Creed concert is what they got.
