I think them losing the venue would be funnier because he would still have to pay for everything else. I doubt the hotel, parties, fighters, filming, etc..
What happens to the PPV? I am sure he would have to refund those five people who bought it! I would imagine there are down payments for using those services, like a small sum they get to even offer it + % on each sale.
Also, imagine if there are fans who bought a flight for this?
Beside the costs, imagine the cope of people constantly bringing up "what is the new date?", from alogs and fans alike!
