Very Poor Customer Service

On Monday 26/10/2020 I went to Kit Kat in Kliptown. I do not have the name of the cashier, but what I can say is that they need to give they're cashiers some very good customer service, they are the most rude public workers I have ever came across, I am disgusted with the way they can treat people and think that it is just fine, and still speak in languages to each other after you speak to them in english....
