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

"When visiting Atenas, it's important to respect the local customs and traditions to avoid any cultural faux pas. Firstly, punctuality is not as strictly observed in Costa Rica as it is in some other countries. However, as a visitor, it's still important to be on time for formal occasions or business meetings. Avoid discussing sensitive topics such as politics, religion, and personal finances. Costa Ricans are generally polite and avoid confrontation, so it's best to steer clear of potentially contentious subjects. In Costa Rica, it's considered rude to point with your fingers. Instead, use your whole hand or nod in the direction you're indicating. Costa Ricans are very friendly and often greet each other with a kiss on the cheek. However, this is usually only between close friends and family, so it's best to stick to a handshake when meeting someone for the first time. It's also considered impolite to refuse food or drink when offered. Even if you're not hungry or thirsty, it's best to accept a small amount to show your appreciation. When dining, it's customary to say "provecho" before starting to eat. This is similar to saying "bon appétit" in French. Lastly, Costa Ricans are very proud of their country and culture. Avoid making negative comments or comparisons to other countries, as this can be seen as disrespectful," remarked another expat in Atenas, Costa Rica.
