LAS VEGAS (CNN) - A California businessman filed a lawsuit against the Downtown Grand Las Vegas Hotel and Casino after he lost $500,000 over Super Bowl weekend.
Mark Johnston said he was invited to stay at the hotel by a casino host. He claimed he had drinks before, during and after his flight to Las Vegas and after checking in to the hotel and during dinner at a restaurant called Triple George.
"They served me all the drinks. They should have cut me off," Johnston said. "Just picture a drunk walking down the street and somebody goes up and just takes their wallet out. That's how a characterize them."
In a civil lawsuit, Johnston claims the casino took advantage of him. He said he has experienced a 44-hour gap in memory where he cannot recall what he did at the casino.
He claimed despite obvious signs of his intoxication, the casino kept serving him drinks and kept allowing him to gamble.
"At some point [the drinking] is my responsibility. But the unfortunately part about it for them is, they have a bigger responsibility than I do," Johnston said. "I am not a sore loser. I've lost a lot of money, I've won a lot of money. This has nothing to do with that. This is about you almost killing me."
Johnston's attorney said Nevada gaming regulations prohibit casinos from letting visibly drunk people gamble.
The Downtown Grand declined to comment about the lawsuit citing a policy to prevents them from commenting on pending litigation. The Nevada Gaming Board is investigating the allegations.
