For Sabahans, such toilet is not something new. Most of us probably have used it before. It is the only toilet that you can enjoy sea vew while doing your business. You also can see a lot of fishes open their mouth wide, waiting under you. Sometimes you can see crab eats crap too.
Before you want to swim in the sea or river which is not near to a tourist site, you better check and make sure no such toilet nearby.
