What cultural faux pas should I try to avoid making in Marine Parade?

"In Marine Parade, it is considered rude to point with your foot as it is seen as the 'lowest' part of the body. Avoid chewing gum in public as it is banned in Singapore. Do not litter, as Singapore is known for its cleanliness and strict laws against littering. Avoid discussing politics and religion openly, as Singapore is a multicultural society with diverse beliefs. Do not eat or drink on public transportation, it's against the law. Avoid touching someone's head as it is considered sacred in many Asian cultures. Always use your right hand for giving and receiving, especially food or money, as the left hand is considered unclean. When visiting someone's home, always remove your shoes. It's also important to respect the queue, as Singaporeans value order and efficiency," remarked another expat in Marine Parade, Singapore.
