It’s common in SA, we have a lot of migrant families and their descendants living here. As I said in the other reply, it is an acceptable word in certain situations but is definitely not widely accepted to direct at strangers. I have seen people take offence to the word across all aspects of life (school, sport, work, etc). Even “reclaimed” slurs can be offensive and damaging, I think it’s important to always be mindful of that.
