Very very bad service

Yesterday(31/01/2013) between 17H00 and 17H30 I went to KFC to buy an Oreo crusher,when I got there they wern't really busy so I went straight to the Cashier @ the counter. While I was there standing right infront of her she yelled NEXT! Calling another customer...nd I was like DAH! Am I invisible? Finally she took my order. I asked 4 an Oreo crusher and she took it straight out of the fridge(Note: she ddnt make one 4 me,I think it was made earlier 4 sum other customer or something)and put it on the counter,handed me my change....ddnt even look me on ma face and yelled NEXT! I took it and walked away because I was rushing to get a bus....but all I'm saying is,that was the most horrible service EVER
