Mook! What's a Mook?
Your money is good enough to take.
What happens to your money after that is a problem?
What if tournament costs go over? That is your problem not the promoters.
If its a accounting issue than delayed payment is better than no payment. Just wait it out.
Prize money can't just be cash in and cash out. People work to run a tournament and they need to address their issues first.
Obviously not a successful business executive or student of business management.
Never take your business's mistakes out on your customer.
