Gambler sues casino on losing $500,000

A Californian man who gambled away $500,000 is now suing the casino management for lending him money while he was drunk.

Mark Johnston, a retired person, is suing the brand new Downtown Grand for loaning him the money and allowing him to play while he was inebriated, Daily Mail reported.

Nevada law bars casinos from allowing visibly drunk patrons to gamble and from serving them complimentary drinks.
