KFC - Rude staff

We went through the Drive trough to buy the Boss Five. The lady at the first window taking our order said we can pay at the next window. When we got to the next window another lady was holding out the Merchant Machine, did not greet us nothing. I explained to her that my card does not have the tap function. she then told us i must reverse the vehicle, by saying go back, go back, not even please, i reversed back. Another lady came and said we must come forward now, also very rude. They said it was because i skipped the window for payment but the lady at the first window said we can pay at the second window. I had a long day at work and did not need this type of treatment from the KFC staff, very disgusted and at the same time disappointed.
