Side of Singapore Tourist Don't See
You don't see this sight at tourist spots, but if you visit residential areas, this is pretty common, especially prevalent in older estates.
Another problem with older estates is some people they don't ever clean their house, when you walk past there will be a stench, then cat feeding, pigeon feeding also a major problem, people just feed strays and then leave the food around, attracting ants, rats and cockroaches.
Also, high rise littering, this morning I heard loud thuds, went to kitchen, somebody threw leftover food out of the window.
So disgusting and filthy.
