Mark Johnston, 52, the retired owner of a southern California car dealership, alleges in his lawsuit the Downtown Grand Casino, which opened under its current name and owners in October 2013, violated Nevada laws by allowing him to play blackjack and pai gow for several hours during a Super Bowl weekend trip to Las Vegas, legaluspokersites.com reported Thursday.

Johnson alleges he was already "blackout drunk" when he arrived at the Downtown Grand and he was comped several drinks and given a $500,000 loan by management to continue gambling. Johnson said he put a stop on the payment of the markers when he emerged from his drunken state on Super Bowl Sunday and discovered how much he had lost. "It's certainly an extraordinary case," attorney Sean Lytte said. "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. It's a very heavy-handed and unusual approach that we haven't seen in this town in a long time."
