Las Vegas Gunman Chased Gambling’s Payouts and Perksbr “It was not a good thing because it would make other VIPs in the high-limit area uncomfortable.”br “One of my guests once said to me, ‘He really gives me the creeps.’”br At Mandalay Bay, Mr. Paddock played the video poker machines located in a relatively quiet roombr labeled “High Limit Slots,” set aside from the jangly machines on the vast casino floor.br But placing bets of $100 or more in video poker, “this guy was gambling high,” said Anthony Curtis, a former professional gamblerbr and currently the owner and publisher of Las Vegas Advisor, a website covering the casino business.br “From all of my discussion with my colleagues it appears Paddock existed in ourbr casino as he did in his neighborhood: as someone not well known by anyone.”br He was better known around a few high-limit rooms of the Las Vegas Strip, including at Mandalay Bay and the Wynn Las Vegas.br “Not a lot of smiles and friendliness,” said John Weinreich, who was an executive casino host at the Atlantisbr Casino Resort Spa in Reno, Nev., where Mr. Paddock was once a regular and where he met his girlfriend.br “He acted like ‘these machines are for me.’”br Mr. Paddock was also a “starer,” Mr. Weinreich said.br “If you get close to 100 percent — that’s where he gambled,” Eric Paddock said.
