LAS VEGAS—Now in the eighth year of his long-term residency at the resort, pop star Bruno Mars reportedly owes the Park MGM $50 million after having assumed since 2016 that the casino cocktails were complimentary. “They’re supposed to be free, right—at least while you’re gambling?” asked the “Uptown Funk” singer, claiming that bar staff across the Las Vegas hotel’s casino, restaurants, and poolside bars never mentioned a tab when offering him another round of drinks, nor did they ever ask for his room number. “I don’t even remember putting a credit card down. They always just said, ‘Very well, Mr. Mars,’ and brought another tray of drinks over. What a scam! If I’d known they were charging me, I would have stuck to the cheap stuff. I’m definitely going to need them to show me an itemized bill for everything before I check out.” Mars later confirmed that where the Park MGM really got him was with the mini bar’s $12 bags of macadamia nuts, which he had been eating continuously for almost a decade.
