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

"In Santa Ana, it's important to avoid discussing politics or the civil war, as these topics can be sensitive and controversial. Avoid making negative comments about the country or comparing it unfavorably to other countries, as this can be seen as disrespectful. It's also considered rude to refuse food or drink when offered, as hospitality is a big part of Salvadoran culture. Avoid wearing revealing clothing, especially in religious or traditional settings, as this can be seen as disrespectful. It's also important to respect local customs and traditions, such as greeting people with a handshake or a kiss on the cheek. Avoid taking photos of people without their permission, especially in rural areas or of military or police personnel, as this can be seen as intrusive. Lastly, it's important to be aware of your surroundings and avoid flaunting wealth or expensive items, as this can attract unwanted attention," remarked another expat who made the move to Santa Ana, El Salvador.
