What cultural faux pas should I try to avoid making in San Juan?

"When visiting San Juan in the Philippines, it's important to respect local customs and traditions to avoid any cultural faux pas. Firstly, avoid discussing sensitive topics such as politics, religion, and personal income. Filipinos are generally polite and may feel uncomfortable with such discussions. Secondly, don't disrespect elders. In Filipino culture, elders are highly respected. Always use polite forms of address and offer your seat to an elder if you're on public transportation. Thirdly, don't refuse food or invitations to eat. Filipinos are known for their hospitality and refusing an offer can be seen as rude. Fourthly, avoid public displays of anger or frustration. Filipinos value harmony and prefer to avoid confrontation. Fifthly, don't point with your feet or use them to move things, as this is considered disrespectful. Lastly, avoid being overly casual or informal in professional or formal settings. Filipinos value respect and politeness, so it's important to maintain a level of formality when appropriate," mentioned another expat when asked about moving to San Juan, Philippines.
