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

"When visiting San Marcos, it's important to respect the local customs and traditions to avoid any cultural faux pas. Avoid criticizing the government or political situation, as this can be a sensitive topic. It's also considered rude to refuse food or drink when offered by a host, as hospitality is a significant part of Nicaraguan culture. Public displays of affection are generally frowned upon, especially in rural areas, so it's best to keep affectionate gestures private. Nicaraguans also value punctuality, so try not to be late for appointments or meetings. When it comes to clothing, it's best to dress modestly, especially when visiting religious sites. Women, in particular, should avoid wearing revealing clothes. Lastly, it's important to remember that the local language is Spanish. While many people speak English, making an effort to learn a few basic Spanish phrases will be appreciated. However, avoid using informal language or slang until you are familiar with its appropriate usage," remarked another expat who made the move to San Marcos, Nicaragua.
