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

"In Paarl, it's important to avoid making assumptions about people based on their race or ethnicity. South Africa has a diverse population and a complex history of racial tension, so it's best to treat everyone as an individual rather than stereotyping them. Avoid discussing politics and apartheid unless you are well-informed about the subject. These topics can be sensitive and may lead to uncomfortable conversations if not handled with care. Do not litter or disrespect the environment. South Africans are proud of their beautiful country and expect visitors to treat it with respect. Avoid public displays of wealth, as this can be seen as insensitive in a country where many people live in poverty. Do not make derogatory comments about the local languages or accents. South Africa has 11 official languages and each one is a vital part of the country's cultural heritage. Avoid being overly loud or boisterous in public places. South Africans generally value politeness and respect for others. Do not disrespect or ignore local customs and traditions. South Africa has a rich cultural heritage and it's important to show respect for this. Avoid making jokes about serious issues like crime or poverty. These are real problems that many South Africans face and making light of them can be seen as insensitive. Do not assume that everyone in South Africa is fluent in English. While many people do speak English, there are also many who do not. Try to learn a few basic phrases in the local language if you can. Avoid being late for appointments or meetings. Punctuality is generally valued in South African culture," mentioned another expat when asked about moving to Paarl, South Africa.
