Who cares if the machine broke? Gambling is about luck. Mostly, the players are unlucky. The machine broke? The casino was unlucky today? Well ... pay up.
I have built for a number of Casinos over the years. On one of the first I made the mistake of using the word "gambling". One of the Casino executives stopped me and said, 'Burke, we don't call it gambling, we call it Gaming. Its not a gamble the way we do it.'
