LAS VEGAS - Las Vegas Sands Chairman and CEO Sheldon Adelson said on Thursday a Hong Kong businessman claiming in a lawsuit that he is owed $328 million didn't help the gaming company get permission from the Macau government to operate a casino there.Richard Suen alleges the Las Vegas company stiffed him on an agreed upon "success fee" for helping secure a permit for a hotel and casino in Macau, a Chinese special administrative territory that has become the world's most lucrative gambling mecca."He couldn't deliver and he wanted to keep his fingers in the pie," the 79-year-old Adelson testified in a Las Vegas court. "Once he couldn't, he wanted to get his fee and offered other services," such as public relations and arranging financing, said Adelson.Adelson, who entered the courthouse on a motorized scooter and looked frail and unsteady as he walked to the witness stand with the aid of a cane, nearly caused a mistrial by presenting promotional brochures for his convention business that hadn't been cleared to be introduced into evidence.
