What the hell is wrong with air conditioning?

Korea's hot, really hot. Not desert hot, but rain forest hot. Humidity rests at about 50% constantly and it rains because it's monsoon season. So, I consider it too fucking hot to work. So we turn on the aircon as the Koreans call it. Yet, there must be something wrong with all these Koreans. They constantly complain that it's too cold. Too cold? I turned it to 60 degrees. Fucking hell man. I'm sweating like a pig, the classrooms have no circulation and I'm getting punchy in class, so I'm sure as shit going to turn on some air to circulate around the fucking room.
I never get complaints. Yet, yesterday I got one for it being too cold in the classroom. What the fuck? This is not a little kid who can't speak English. No, this is one of my highest level students who doesn't tell me this himself. No, he has his mommy call and let me know. So what should I do? Not turn on the AC? Then what if every other kid complains that it's too hot? There's no way I'm going to cater to this one kid. Sorry, it's summer and we have AC. Get used to it. Fifteen other kids in the class trump one kid's discomfort. And besides, it's always the kid in tank top and shorts, sitting right next to the AC who complains. Of course it's too cold. You're sitting in it asshat.
