Horrible customer experience

I went to THOKOZA unit F usave 10 min ago I was doing a cash send and and buying water and juice and the cashier didn’t even greet me , and there was no smile , smile is not even a must , but to show that she is willing to serve customers, she was angry 😡 , I didn’t even mind that she didn’t greet me , but assist me , here I am giving her my number I have never done a cash send before it was a first time , and I was supposed to have given her a ref and she banged her hand on the counter, I snapped I told her don’t get agitated with me , she went on with her tantrums , I spotted a guy that seemed like a superior I told him your cashier seemed frustrated and she must live that at home observe from afar , before I even live the store I over heard him saying look at this man he is making himself a white person , to me he looked at me and he said look at this stupid, he was buying my face not what I was saying, a horrible service from cashier and manager , spoiled the happy mood I had , I had a very but very bad experience in that store,
