Last time, no one dare to eat and drink in bus or mrt unless got $500 spare. I didn't even dare to have mentos in my mouth.
Now, honestly speaking, ppl can eat whole fast food value meal without anything serious happen. At most got stomped or got told off by mrt staff or bus driver. No one's enforcing that anymore. Even if there are, the perpetrators tend to be more ball-full than the enforcers.
Singapore was a fine city, now it's an empty threat city... Of course for some, they still feel the full force of the law, but that's another story.
We all can reflect all we want, but when there's no real consequences even to some minority group, people tend to be behave unruly regardless they are SG, PRC, HK, US, JAP or whatever.
Back to the cat and dog, they should be flogged when they poop on your sofa, regardless whether the owner is your local MP or the poor homeless uncle at the void deck. Be it a common mongrel or it's a million dollar pure breed cat or dog. At most SPCA will look for you with some boys in blue nia.
