In Singapore, not flushing after using a public toilet is punishable by a $150 fine
Keeping Singapore as clean as it is is a top priority for the city-state. Make sure you follow the first guideline while seeking a public restroom if you can’t keep your trousers up (when it’s time to go, it’s time to go). When you’re done, don’t forget to flush.
Public toilets in Singapore come with a $150 punishment for not flushing, and those who refuse to pay the charge face incarceration.
