Bad service

I was at your Checkers Wonderpark on 18/02/2022 proceeded to your till point at 18:31. As I got by the queue your Cashier Elelwani Tshakafa raises her voice at me and say 'You must'nt let anyone to stand after you on the queue'. I told 2 more customers that came then it happenes d I missed the 3rd one. She saw this and screamed again 'I said you must'nt let anyone after you' in her aggresive voice. As I got to the till I made it clear to her that I was'nt at the shop to do her job, I was only there to do my shopping'. With an attitude she then said 'e fetile'. She spoke about me to the client she assisted before me. Checkers retrain your staff when it comes to service, let them know what they can ask of clients and they cannot. This is just ridiculous.
