What cultural faux pas should I try to avoid making in El Tunco?

"In El Tunco, it's important to respect the local customs and traditions. Avoid making negative comments about the country, its people, or its culture. El Salvadorans are generally conservative, so avoid wearing revealing clothing, especially in religious or traditional settings. It's considered rude to interrupt someone while they're speaking, so always wait for your turn to speak. Avoid discussing sensitive topics such as politics, civil war, or gang violence, as these can be sensitive subjects for many Salvadorans. It's also considered impolite to refuse food or drink when offered by a host. If you have dietary restrictions, explain them politely. Public displays of affection are generally frowned upon, especially between same-sex couples, as El Salvador is a predominantly Catholic country with conservative views on sexuality. Avoid pointing with your finger, as this is considered rude. Instead, use your whole hand to gesture. Lastly, always remember to say "please" and "thank you". Politeness is highly valued in Salvadoran culture," said another expat in El Tunco, El Salvador.
