IT'S happened again. Another innocent man who just wanted a few lap dances claims to have been victimized by an exclusive New York strip club, Scores. This time it's an executive from Missouri named Robert McCormick, who, treating himself and friends, ran up a $241,000 bill at Scores on his corporate American Express card two years ago. American Express is now suing him for refusing to pay up. Several other unhappy customers have also sued Scores over large bills.
