It reminded me of any South American Davis Cup tennis event. The fans have the English Soccer mentality. It should be the same in the upcoming beach volleyball events. They don't intend any disrespect, they are just really passionate about wanting their team to win.
Glad there's a pole vault thread hear. The Brazilian cleared 19-9 by six inches, then didn't jump again, after he locked up the gold. Tough call whether to quit with a successful jump, or go after 20' while you're hot. He's metric, and got the new Olympic record, so maybe 20 didn't mean much to him. But with his last vault, a world record was not out of the question.
