Appalling and ridiculous by staff at McDonald's

Hello Peter, On Saturday (05/09/2020) I went to MacDonald (Restaurant #***) in Menlyn to get something to eat with my friends. I went to the drive through where I was assisted by a lady called Winnie (crew ID 14), I was not happy with the service that I received from Winnie as she thought we just came to the establishment to play games and never took the order when she was spoken to on the intercom outside. The order was for a 1 Share Box Beef, 10 McNuggets, 2 regular cokes and 2 small cokes to a total value of R187. She confirmed the order on the intercom, however she did not punch it on the system for the food to be prepared. When I got to the window to make a payment she then told me that she didn't place the order and she thought that I was joking because I kept on talking in the car. My question to her was that "would I come all the way to McDonalds to waste my time and place with her on the intercom when she is supposed to take an order?".

She had one simple thing to do which was to take an order and place it on the system then process a payment, the other things that happen in the car have nothing to do with her and it is none of her business. I further escalated the issue to Ouma who was the shift Leader on that day and I told her of how I was not satisfied with the level of service that I received from Winnie and Ouma said that she would address the issue. I would like to know what happened with my case and if Winnie was called to book, I am very sure that if I was a white customer I would not have received such a service. But because I am a black customer I was taken for a fool and for granted, especially after Winnie burst out in laughter when I confronted her about the situation - that just got me annoyed and I even told Ouma that if Winnie does not want to work then she should stay at home and make way for other people that need the job more than she does. I want to know what measures were taken to make the staff to understand that McDonald's need customers for the business to be functional and customers should be respected at all cost. This is just unacceptable and appalling for a brand as big as McDonald's to have *********** staff facing customers everyday and not taking the very same people who bring business. I need an apology from Winnie and nobody else, she needs to learn a lesson of what a customers is.
