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

"In Pretoria, it is considered disrespectful to not greet someone before starting a conversation. Always begin with a simple "hello" or "how are you". Avoid making negative comments about the country's political situation or history, especially about apartheid. These topics are sensitive and can lead to uncomfortable situations. Do not assume that everyone in Pretoria speaks English. While English is widely spoken, the city is multicultural and multilingual, with many residents speaking Afrikaans or indigenous languages. Avoid using your left hand to give or receive items, as this is considered disrespectful. The right hand is traditionally used for these actions. Do not make assumptions or stereotype based on race or ethnicity. South Africa is a diverse country with a complex history, and such behavior is considered highly offensive. Avoid public displays of affection. While South Africa is relatively liberal, it is still a conservative society and public displays of affection can be seen as disrespectful. Do not take photographs of people without their permission. This is considered rude and invasive. Avoid littering. South Africans take pride in their country's natural beauty and littering is frowned upon. Do not enter someone's home with your shoes on unless invited to do so. It is customary to remove your shoes when entering a home. Avoid being overly loud or boisterous in public places. South Africans value respect and courtesy, and such behavior can be seen as disrespectful. Do not disrespect the local customs and traditions. South Africa has a rich cultural heritage and locals appreciate when visitors show respect and interest in their customs. Avoid discussing personal wealth or income. It is considered impolite to discuss money matters in social settings. Do not ignore queues. South Africans are generally orderly and respectful of queues, whether it's for public transport, at the supermarket, or elsewhere. Avoid making jokes about wildlife or safari as not all South Africans have these experiences. It's a stereotype that all South Africans have lions in their backyard, which is not true and can be offensive," said another expat in Pretoria, South Africa.
