Complaint bad service

I had the worst experience ever on the 04/12/2022 at 19h15. I used the drive through at Njoli when I got to window to pay the guy told me that the merchant machine was out of order and I had to pay cash. I didn't have a problem with that so I searched through my purse knowing that I do have notes. The way he shouted at me telling me I must come and pay inside the store and make quick as I am waiting his time he is in a hurry even showing to his wrist. I said to him he might as, well cancel my order and I left. I have never experienced such rudeness I also work in a customer facing environment and u can never ever speak to a customer in such a manner. I would not recommend that KFC to anyone and I will never ever buy there again.
