What cultural faux pas should I try to avoid making in Serangoon Gardens?

"In Serangoon Gardens, it's important to respect the local customs and traditions. 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. When using public transportation, do not eat or drink as it is prohibited. Always stand on the left side of escalators to allow people in a hurry to pass on the right. Avoid pointing with your index finger, as it is considered rude. Instead, use your whole hand to gesture. When visiting religious sites, dress modestly and remove your shoes before entering. Do not touch someone's head as it is considered sacred. Avoid discussing politics and religion in casual conversations as these topics can be sensitive. In dining etiquette, do not stick your chopsticks upright in a bowl of rice as it is associated with death. Always wait to be invited before starting to eat and do not take the last piece of food from a communal plate without asking. Lastly, always address elders with the proper honorifics as a sign of respect," remarked another expat in Serangoon Gardens, Singapore.
