Fans should be ashamed of their behavior at last night's U.S. Open feature match

Whenever someone plays a French player at the French Open, I am always disgusted by the behavior of the French fans, who cheer when the opponent hits a service fault or makes an unforced error. Last night, during the Agassi/Pavel match at the U.S. Open, Americans made the French look polite. They not only cheered loudly when Pavel made a service fault or hit an unforced error, but they booed whenever he stepped up to the service line. At times, the booing was so loud, Pavel had to wait before he could serve. At one point, before Pavel's serve could be executed, someone yelled out "Fuck you, Pavel!" The chair umpire did little to stop this display. I did notice that Agassi was more restrained than usual in thanking the crowd for support, but I wish he had told them to stop acting like the ill-mannered pigs they were.
