“Alcohol, though strictly prohibited by Saudi law and custom, was plentiful at the party’s well-stocked bar. The hired Filipino bartenders served a cocktail punch using sadiqi, a locally-made moonshine,” the cable said. “It was also learned through word-of-mouth that a number of the guests were in fact ‘working girls’, not uncommon for such parties.”

The dispatch from the US partygoers, signed off by the consul in Jeddah, Martin Quinn, added: “Though not witnessed directly at this event, cocaine and hashish use is common in these social circles.”

The underground party scene is “thriving and throbbing” in Saudi Arabia thanks to the protection of Saudi royalty, the dispatch said. But it is only available behind closed doors and for the very rich.
