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

"In Machala, it's important to avoid discussing sensitive topics such as politics, religion, and personal income. These topics are considered private and it's considered rude to bring them up in casual conversation. Avoid being overly direct or confrontational. Ecuadorians tend to communicate in a more indirect manner and value harmony in social interactions. Don't be surprised or offended if someone is late. Punctuality is not as strictly observed in Ecuador as it might be in other cultures. Avoid wearing revealing clothing. Ecuador is a predominantly Catholic country and modesty in dress is appreciated. Do not litter. Ecuadorians are proud of their beautiful country and take environmental conservation seriously. Avoid making negative comments about the country or its people. This is considered disrespectful and could offend locals. Do not refuse food or drink offered to you as it can be seen as disrespectful. It's better to accept and then leave it untouched if you don't want it. Avoid public displays of affection. While it's common for friends and family to greet each other with a kiss on the cheek, excessive public displays of affection are generally frowned upon. Do not rush or push in lines. Patience is highly valued and it's considered rude to rush or push ahead of others. Avoid using your left hand to give or receive items. This is considered impolite. Always use your right hand or both hands," said another expat in Machala, Ecuador.
