kfc staff degrading the brand

Went to Kfc thembisa branch 6-30am to buy 3 kiddies meals for my children's school trip went to drive thru hooted the bell for about 10min no reply went inside the shop where there was no staff till one staff had to get the rest of the staff which was asleep I could tell as they were yawning and stretching in the kitchen which is within customers view. Other customers who came after me were attended 1st simply because they caused scenes. I tried calling the number on the till slip *** which doesnt even work and when I asked the girl named Portia as to why she had the nerve to say its my phone and their phone isnt on voice mail I felt so provoked once the order was done I had to ask for a carry bag be cause she gave me three meals and was expected to carry with no carry bag. I felt so angered as they underestimated me because im young whereas older customers that were complaining were attended to with urgency.. now I was 5min late to my childrens school where they were going on a school trip and we had to stop the bus as it was about to leave
