Poor Service

On the 4th August 2021 around 19:36. I went to KFC Ntshongweni in Katlehong. Firstly there was a long queue in the drive thru, when it was my turn to buy I would hear that the ordering intercom is working but there was this male employer wearing full KFC uniform who was taking orders. I ordered two streetwise two with chips, he told me that they do not have Streetwise two but have Streetwise 3 and Streetwise 5, so my next question was how, I did not get an answer instead he looked in my arm and saw a R100 note and tried to convince me to buy Streetwise 5 of which I told him NO I want Streetwise two by 2. So I ended up ordering Streetwise 3 of which I did not want. I then proceeded to pay when I got there the lady at the till gave me a slip before she could see how much I had on me then when I gave the money she gave me R50 back, I asked her is this how you work give people slips before they give you money and how did you know that I had how much, cause I swear I did not see you punch in my order, she was shaking and did not give me a straight answer. I went to get my order on the next window and asked the guy who was serving my order do you have Streetwise Two and he said yes we do have. So my question is exactly what is happening from the ordering to the pay window. It seemed so shady and I ended up ordering what I did not want. POOR SERVICE SERIOUSLY.
