What cultural faux pas should I try to avoid making in Pasay City?

"It is important to be mindful of cultural norms when visiting Pasay City. It is considered rude to point with your index finger, so it is best to gesture with your whole hand. It is also important to dress modestly, as showing too much skin can be seen as disrespectful. Additionally, it is important to be aware of the local language and to avoid speaking English too loudly in public. Finally, it is important to be respectful of religious sites and to avoid taking photos without permission," remarked another expat in Pasay City, Philippines.
