Nick Binger's brother Michael, Michael's agent, and other friends ordered a couple bottles of champagne a little earlier. By time the bottles got to the stage area, Nick had lost his chip lead and is struggling to get his footing back. We don't know for sure if the champagne was in preparation for Binger's possible bracelet or if the spectators just wanted to sip the bubbly, but it could be the jinx keeping Binger from climbing.
Binger's railbirds can be seen with elegant glasses in their hands, filled with the light golden liquid, sipping away as they root on Nick.
