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

"Franschhoek is a multicultural town with a rich history, so it's important to respect all cultures and traditions. Avoid making derogatory comments about any racial or ethnic group, as South Africa has a history of racial tension. It's also considered rude to interrupt someone while they're speaking, so always wait your turn in conversations. Avoid discussing sensitive topics such as politics and religion unless you are well-informed and the conversation naturally leads there. South Africans are generally open and friendly, but they also value their privacy, so avoid asking personal questions unless you know the person well. In Franschhoek, which is known for its wine, it's considered impolite to refuse a drink when offered, unless you have a valid reason such as being the designated driver or having a health issue. However, it's also important to drink responsibly and not to overindulge. When visiting someone's home, it's customary to bring a small gift, such as a bottle of wine or flowers. If you're invited to a braai (South African barbecue), offer to bring something to contribute, such as a salad or dessert. Finally, remember to respect the environment. Franschhoek is located in a beautiful part of South Africa, and locals take pride in preserving their natural surroundings. Don't litter, and always stick to designated paths when hiking or exploring the countryside," mentioned another expat when asked about moving to Franschhoek, South Africa.
