Rude Manager at Wimpy Flora Centre Johannesburg

My husband took me to Wimpy in Flora Centre Johannesburg for breakfast on the 24th January. I know it's COVID but the size of the meals for the amount of money was ridiculous. I was terribly disgusted by the Manager, Phindile, we queried a tax amount on our bill. When we spoke to her she said in Zulu that my husband was crazy and rude. The way she explained it to him by scratching on our bill and walked away from him while talking. She did not know I could understand Zulu.
