seriously bad service

I work at the same center as this kfc, i quickly popped out of the shop to go get some quick breakfast at kfc, i got there and there was only one cashier, she was taking a ladies order, everything is done very slowly. she took the order and gave her her change, then looked straight at me and walked into the back of the kitchen. so i waited for her, she came back to the front looked straight at me again and the proceeded to walk slowly to the back of the kitchen. i waited for about 10 minutes or which is time i cant spare out of work, and she still just looked at me and didnt take my order. this is such bad service i am actually disgusted and i wont be going back there again.
