Spitting gum on the street (littering) is punishable by a S$300 fine if my memory serves me correctly. No caning for littering.
I don`t know, I read something a while ago that they whip your butt for that, but I`ve never been there before nor do I intend to. Can you imagine that happening here, butt whipping for grafitti or whatever it is? Forgeeeet it, you`d have ambulance chasers blocking up the courts for decades not to mention liberals going into seizures. You can`t even whip a serial killer in the US! Matter of fact, not only do we not whip them, we (Hollywood) makes movies about them and celebrates them on Oscar night.
