Reminds me of the ROK Marines on a U.S. LST in the early 80's. The ROK Marines would squat on the toilets and not flush and when they did flush, after the toilet was full to over flowing, there was poo everywhere. The ROK Marine's Sergeant Major got on the ships intercom and talked to his Marines for about 45 minutes to an hour. After that there was no more trouble.
Oh, and while the Sergeant Major spoke the ROK Marines all stood at attention.
