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

"When visiting Antigua, it's important to respect the local customs and traditions. Avoid wearing revealing clothing, especially in religious sites, as it is considered disrespectful. Do not take photos of locals without their permission, as it is seen as an invasion of privacy. Avoid making negative comments about the country or its people, as Guatemalans are very proud of their heritage. It's also considered rude to refuse food or drink when offered, as it's a sign of hospitality. Do not litter or damage any historical sites, as these are considered national treasures. Avoid discussing sensitive topics such as politics, religion, or the country's past conflicts unless initiated by locals. Always greet people with a polite "Buenos días" (Good day) or "Buenas tardes" (Good afternoon) before starting a conversation. Lastly, remember to be patient and understanding, as things may not always run on time or as efficiently as you may be used to," said another expat in Antigua, Guatemala.
