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

"It is important to be respectful of Zimbabwe's culture and customs when visiting. It is considered rude to point with your finger, so it is best to gesture with your whole hand. It is also important to dress modestly, as revealing clothing is considered inappropriate. It is also important to be aware of the local customs and beliefs, and to avoid making any comments that could be seen as disrespectful. Additionally, it is important to be aware of the local language and to avoid speaking in a loud or aggressive manner. Finally, it is important to be aware of the local customs regarding gift-giving, and to avoid giving gifts that could be seen as offensive," mentioned another expat when asked about moving to Zimbabwe.
