A visionary Singaporean couple has been hailed as environmental activists after donating several kilograms of premium household waste to a Johor Bahru parking lot.

The duo reportedly felt the Malaysian landscape was looking dangerously tidy and decided to intervene with a red plastic bag of justice.

“Walao, in Singapore if I throw one tissue also kena fine five hundred, you know?” explained the male passenger, an expert in tactical littering.

“JB is basically just a giant green bin with cheaper petrol, so why not?”

The local garage operator was reportedly stunned by this display of "Sinkie excellence," failing to appreciate the gift of discarded plastic spoons.

Experts suggest this is a biological reflex where Singaporeans must purge years of suppressed delinquency the moment they smell cheaper 95-octane fuel.
