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

"In Nosara, it's important to respect the local customs and traditions. Avoid making negative comments about the country or its people, as Costa Ricans are very proud of their heritage and culture. It's considered rude to point with your fingers, instead use your whole hand to gesture. Avoid discussing sensitive topics such as politics, religion, or personal finances, as these are considered private matters. It's also considered impolite to raise your voice or show anger in public, as Costa Ricans value peace and tranquility. When dining, it's customary to say "provecho" (enjoy your meal) before starting to eat. Leaving food on your plate can be seen as wasteful, so try to only take what you can finish. Punctuality is not strictly observed in Costa Rica, so don't be offended if locals are late to appointments or social gatherings. Lastly, Costa Ricans are very environmentally conscious, so avoid littering or damaging the natural environment," mentioned another expat when asked about moving to Nosara, Costa Rica.
