You already did. And if you are really an Indonesian, you should correct your crowd, not support their rather distasteful actions. Got nothing to do with what fan I am or not. As I say, show me a situation that something a like happens so continuously, and it will be disgusting for me.
booing is disgusting to me too whether done in india or china or mars.I didn't enjoyed the drum sounds during sudirman cup.
Could be cultural. Apparently in China, it's very common for people to spit in public. One of my friends said you'd see a good looking girl walking around and then suddenly she'd spit randomly on the floor. If you did that in Singapore, you'd get arrested and beaten in a jail cell.
Funny, it seems that the noise disturbed some of the fans more than the players themselves. Relax guys, Indonesia Open has been held since 1982, and I believe all participants already know how Indonesian crowd behaves.
Okay, in this video of Sudirman cup final you can watch the crowd disturbing JPN players while about to serve https://www.youtube.com/watch?v=7ap-XeeHOkM
