I fail to see what the problem is. Is it because the fight was to short/ not long enough? It was a fight, not a football game. There is no rule saying how long a fight must be except by round. Anyone who paid to see this did get their money's worth. The fact that it was 2:30 is irrelevant. It was a fight. Not a movie. Not a football game. Not ballet.
You pay your money. You take your chances.
