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

"While visiting Wilderness, it's important to respect the local customs and traditions. Avoid making derogatory comments about the country, its people, or its political situation. It's considered rude to start eating before everyone has been served or before the host starts eating. When greeting someone, a firm handshake is the norm, but wait for a woman to extend her hand first. Avoid touching someone without their permission, as personal space is highly valued. It's also considered impolite to refuse food or drink offered to you during a meal or gathering. However, be aware that it's customary to refuse the first offer as a sign of modesty. Avoid discussing sensitive topics such as apartheid unless initiated by locals. It's a painful part of their history and can be seen as disrespectful. Littering is frowned upon, as South Africans take pride in their beautiful landscapes. Always dispose of your trash properly. Lastly, remember that punctuality is not highly stressed in South African culture. Being a few minutes late is generally acceptable, but it's always better to be on time for formal occasions or business meetings," mentioned another expat when asked about moving to Wilderness, South Africa.
