Was in Singapore for a couple months a while back. The law is the law and they enforce it like they mean it. Even littering will land you in front of a judge. Borderline authoritarian, but one of the very lowest crime rates in the world.
And in regards to littering, it is hands down one of the cleanest major cities I’ve ever seen.
Laws are useless unless enforced.
They are just virtue signaling without it.
Complete order is easy if the government is willing and powerful enough to impose it.
“Chewing gum is banned in Singapore so leave it at home when packing your bags. Importation of chewing gums into the country, even if it is not for trading, is illegal.”
“Not flushing the toilet is more than just a breach of propriety in Singapore, you will be breaking the law if you do so.”
