Racial abuse from Coconut seller at Fourways Farmer's Market

Yesterday my friends and I went to Fourways farmer's market and have decided we will never go there again. There was a black man there selling coconuts, who racially abused two Asian youngsters. I had just bought a coconut from him so I was right there when he shouted "hey Chinaman!" to the two Asian youngsters. I was absolutely horrified, I immediately asked him to apologize to them and he refused. He said "I don't even care if they buy from me or not". It was a very sad day for me as a black woman to hear such racial abuse from my own people, meanwhile I have traveled all over the world and have never been racially abused anywhere. I hope that man gets removed from the Fourways farmer's market.
