“Sin City” is chock full of stories of gamblers who lost big — and partiers who had a little too much to drink. One man, however, thinks he shouldn’t have to pay for his gambling losses because he was so drunk, and is suing a Las Vegas casino to recoup his losses.

Screen Shot 2015-01-23 at 2.48.46 PMThe Associated Press reports that California resident Mark Johnston, who lost $500,000 in table games during Super Bowl weekend, is “suing the Downtown Grand for loaning him money and serving him drinks when he was visibly intoxicated.”

Johnston says he was thoroughly drunk during the hours he spent playing pai gow and blackjack at the Grand. His legal team plans to rely on eyewitness testimony and surveillance video to prove that he was visibly intoxicated.

The state Gaming Board is reportedly investigating the situation.

“It’s certainly an extraordinary case. This is not a story that I’ve ever heard before, where someone was blackout intoxicated where they couldn’t read their cards, and yet a casino continued to serve them drinks and issue them more markers,” said Johnston’s attorney.

Extraordinary case, indeed. Some would say, “ridiculous.”
