Man sues the Downtown Grand in Las Vegas, says he was drunk when he lost $500,000

A man who lost $500,000 playing table games at a Las Vegas casino on Super Bowl weekend is trying to get his money back because he was too drunk. Southern California retiree Mark Johnston is suing the Downtown Grand for loaning him money and allowing him to play while he was blackout drunk. Nevada law bars casinos from allowing visibly drunk patrons to gamble and from serving them comped drinks.
