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

"When visiting Playa Grande, it's important to respect the local customs and traditions to avoid any cultural faux pas. One of the first things to remember is to avoid littering. Costa Rica is known for its commitment to the environment, and locals take pride in keeping their surroundings clean. It's also considered rude to raise your voice or show anger in public. Costa Ricans value peace and harmony, and public displays of anger can be seen as disrespectful. When dining, remember that Costa Ricans typically eat their largest meal at lunch, not dinner. If you're invited to someone's home, it's polite to bring a small gift, such as flowers or chocolates. Avoid discussing sensitive topics like politics, religion, or personal finances unless you know the person well. It's also considered impolite to ask direct questions about someone's income or personal life. Costa Ricans are generally punctual for business meetings, but social events often start later than scheduled. Don't be surprised if you're invited to a party at 8pm and most guests don't arrive until 9pm or later. Finally, remember to respect the local wildlife. Playa Grande is known for its sea turtles, and it's important not to disturb them or their nesting sites," remarked another expat who made the move to Playa Grande, Costa Rica.
