Extremely Bad Service from Busi,

I went to Nando's Ghandi Square for lunch as usual. The restaurant has three till machines, and when it was my turn to buy, Noma (the cashier) called for me to come and buy on the middle till. A customer who had been ordering from the first till came and started ordering where I was, surprised that I was busy. Busi told me to move back to the queue and cancelled my order, starting to help her customer that she was helping on the first machine. I then moved back to the queue, After returning to the queue, I was called to the third machine once more. As I was placing my order on the third till, the kind man interrupted me once more without providing an explanation. I was instructed to return to the queue for a second time, but when I refused, I was informed that the other two machines were no longer operational. Busi and her customer forcefully remove with a foul attitude and arguments. Only then did another cashier ask me to make a purchase using the middle till, which they said was no longer operational. I RECOMEND SHE MUST BE CHANGED TO ANOTHER BRANCH WITH HER BAD CUSTOMER SERVICE, so now i have to change nando's branch because of her stinky attitude.
