plz send your stalf for training

I pulled up along side the petrol pump. Waiting for the attendant, I hear shouting in sesotho behind me. l look back. I see jackson. I got out of my van. I look around. I see only him. I asked him why is he shouting at me in a language I do not understand?speak to me in english or afrikaans. Rudely he says he can speak to me in any language he chooses! I told him I will report this and he very confidently says go ahead and report to the manager, so I just drove off. Its not a big loss as I was only filling a R100.
