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

"It is important to be respectful of Haitian culture and customs when visiting the country. It is best to avoid making any negative comments about the country or its people, as this can be seen as offensive. Additionally, it is important to dress modestly and to avoid taking photographs of people without their permission. It is also important to be aware of the local customs and to be respectful of religious beliefs and practices. Finally, it is important to be aware of the local language and to avoid using slang or profanity," remarked another expat in Haiti.
