Extremely rude clicks worker

Yesterday I encountered a very strange and rude clicks worker at clicks denlyn in mamelodi. His surname is Mokoena (if I'm not wrong his name is Mokone). He found me speaking to a pharmacist assistant trying to find a roll-on thats good for a 7 year old. He then got to us, didn't greet and in a loud and rude voice asked the pharmacy assistant what I wanted (the question was very very rude). As in "what does this one want" (exact words are " a re o batlang"). The lady explained what I wanted and he said to me. "In our pedi culture we take ash from the fire that we make on the ground and apply it on the armpits. I should do the same, I then asked where am I going to find ash and he said I shouldn't ask him that, I can go to the ladies who sell fat cakes in the street and ask them. Then he left. I was so shocked and so was the pharmacist assistant. Can clicks look into this and take the necessary steps. And for the record, I'M NOT EVEN PEDI!
