I HAVE FOUND THAT THE "TIP" IS THE SECRET. PICK A TIME WHEN THE PLAYERS CLUB IS NOT BUSY; MAYBE WHEN THE SUPERVISOR IS ON BREAK; TELL THE PERSON YOU NEED TWO BLANK CARDS AND SHOW, SAY, A DOLLAR BILL ( IF IT'S A CARD YOU REALLY WANT, HAVE A $5 DOLLAR BILL IN YOUR POCKET READY JUST IN CASE ). WORKS MOST OF THE TIME. GOOD LUCK!
