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

"While visiting Flores, it's important to respect the local customs and traditions. Avoid wearing revealing clothing, as it can be seen as disrespectful in this predominantly Catholic country. Always ask for permission before taking photos of people, especially indigenous people, as it can be considered intrusive and disrespectful. Avoid making negative comments about the country or its people, as Guatemalans are very proud of their heritage and culture. Do not litter or damage any natural or historical sites, as these are highly valued by the locals. Try not to haggle too aggressively in markets, as this can be seen as disrespectful. Avoid discussing sensitive topics such as politics, civil war, and indigenous rights, as these can lead to uncomfortable conversations. Lastly, always greet people with a polite "Buenos días" (Good day) or "Buenas tardes" (Good afternoon) before starting a conversation," remarked another expat in Flores, Guatemala.
