What cultural faux pas should I try to avoid making in EAST COAST?

"When visiting the East Coast of Singapore, it's important to respect the local customs and traditions. Avoid pointing with your foot, as feet are considered the lowest and dirtiest part of the body in Singaporean culture. Also, avoid touching someone's head, as it is considered the most sacred part of the body. When using chopsticks, do not stick them upright in your bowl of rice, as this is associated with funerals. Also, do not pass food with chopsticks directly to someone else's chopsticks, as this is also a funeral rite. In Singapore, it's considered rude to chew gum in public, and it's actually illegal to sell gum in the country. So, avoid bringing gum into the country or chewing it in public places. When visiting religious sites, dress modestly and remove your shoes before entering. Also, avoid taking pictures without permission, especially in religious sites. In conversation, avoid discussing sensitive topics such as politics, race, and religion. Singapore is a multicultural society with diverse beliefs and opinions, so it's best to steer clear of potentially controversial topics. Lastly, Singapore is known for its strict laws and cleanliness. Littering, jaywalking, and vandalism are all punishable offenses, so be sure to respect the local laws and keep the city clean," remarked another expat in EAST COAST, Singapore.
