There is a news report on filthy public restrooms albeit without photos . Here: http://www.thestar.com.my/News/Nation/2014/11/23/Malaysians-fed-up-with-typically-filthy-facilities/
I agree with what was mentioned by those interviewed. Let me show you some pics I took not too long ago. All these toilets stank. Yuck!
When you really need to answer the call of Nature in the public, you just have to put up with it.
