imposed restrictions on what Sinatra could gamble in the casino, to just $3,000 a night. Under previous management, Sinatra had no limits on the amount of credit extended to him by the Sands casino. His IOUs, chits or "markers" were torn up at the end of Sinatra's engagements because he was considered to be good for business—bringing the hotel more monetary value than the worth of his gambling losses. Hughes put a stop to this system, telling Jack Entratter to inform Sinatra of the new policy; Entratter did not do so because he was afraid. Fuming, Sinatra began what The Los Angeles Times describes as a "weekend-long tirade" against the "hotel's management, employees and security forces." The FBI report says the incident began when Mia Farrow lost $20,000 at the Sands casino. Sinatra bought $50,000 in chips and made an attempt to win the money back. He lost this sum within a short period of time. Sinatra then asked for credit, which was denied. It culminated when Sinatra reportedly drove a golf cart through the window of the coffee shop where casino manager Carl Cohen was seated and began "screaming obscenities and anti-Semitic remarks" at Cohen. Sinatra reportedly punched Cohen, a heavily built man, who responded with a smack in the mouth, bloodying Sinatra's nose and knocking two of his teeth out. As a result, Sinatra never performed at the Sands again while Hughes owned it, and began performing at Caesars Palace. A number of the staff were not disappointed to see Sinatra leave the Sands. Numerous employees had been humiliated or intimidated over the years, including a busboy Sinatra tripped while he was carrying a tray with dishes. After Sinatra left, the mobsters pulled out of the Sands and gradually left Vegas in the 1970s. In the 1970s, it became associated with the likes of Wayne Newton and Liberace. At this time, some 30% of the performers at Sands were Italian Americans. Frank Gagliardi became the drummer for the house orchestra in 1964, starting a twelve-year tenure. In 1968, Hughes stated that he intended to expand Sands into a 4,000-room resort, but his plans did not materialize. In 1983, Hughes' company, the Summa Corporation, sold the Sands to the Pratt Corporation, but subsequently bought it back as they were unable to make a profit. MGM Grand, Inc. bought the hotel along with the neighboring Desert Inn in 1988 for
