Well Watanabe obviously has gambling problems... the casino should not have allowed him to stay and gambling, at the same time though, he should have been able to stop himself.
It is not the casino's fault.
A casino is a business based on people loosing. This guy lost $127million, its a lot but why should the casino be expected to turn away their biggest customer?
If they said "Mr Watanabe, you have lost a lot, we are going to stop you from playing for the next few days", Mr Watanabe isnt going to say "gee thanks you really stopped me from loosing everything", Mr Watanabe is going to get his stuff and go to another casino who is willing to let him gamble with his $127 million.
People seem to think .. well the guy was drunk so maybe he should get back his money. Those people should consider the reverse of this. If someone wins a lot of money at a casino, can they breathalyse him, and if he turns out to be drunk, can the casino have their money back?
This is a man who lost $127 million over the course of 12 months. He knew what he was doing but exercised no personal responsibility. Now he realises that $127 million is a lot of money to loose, he thinks he should have it back. This man is an idiot.
