DIMISILE, work on your customer interaction

On the date 13 December 2017, 11:27 an employee named Dimisile, cashier 23, was incredibly rude towards me. I had a total amount of 3, including airtime. I was standing at the tills, and most of the operating ones had 2 or more occupants. I decided to go to the kiosk because I was in a rush, it had no customers before I approached it. By the time I got there, there was an employee paying for her items. Dimisile was happily chatting to her collueage while she processed her items. When it was my turn, she didnt greet me, her attitude had changed from the time she was speaking to her colleague. She asked my why had I not paid at the till point instead. I told her there were people there when I left and I was in a rush. She said I should have paid there (Till), I told her I was here already (kiosk). Her tone changed and she yelled, "Don't say you're here already, you should ask me to pay here!" in isiZulu. I dont care if she was having a bad day and had to take it out on someone, I am a paying customer. If she feels like she is the kiosk police, she needs to notify us. If she really felt strongly about people paying at till points, she should her told her colleague and the customer that followed me. She didn't ask either of them why they hadn't paid at the till points. There have been several times I paid at the kiosk and I didn't get this melodrama.
