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

"San Marcos La Laguna, is a small town known for its indigenous Mayan culture and a growing international community. When visiting, it's important to respect the local customs and traditions to avoid any cultural faux pas. Firstly, avoid taking photos of the locals, especially the indigenous Mayan people, without their permission. It's considered disrespectful and intrusive. Secondly, refrain from bargaining too aggressively in the local markets. While haggling is a part of the culture, being too aggressive can be seen as disrespectful. Thirdly, avoid making negative comments about the local customs or traditions. The Mayan culture is rich and deeply rooted, and any negative comments can be seen as offensive. Fourthly, dress modestly, especially when visiting religious sites. The local culture is quite conservative, and revealing clothing can be seen as disrespectful. Lastly, avoid littering or causing any environmental damage. The locals take pride in their natural surroundings, and any harm caused to the environment is taken very seriously," remarked another expat who made the move to San Marcos La Laguna, Guatemala.
