I received a McDonld's coupon booket in the local Sunday newspaper and decided to use it. The coupons just started today 8/30/09. I went to the drive thru and ordered my 20-pc Chicken McNuggets and made her aware that I had a coupon. The price on the screen stated a much higher price than coupon. I told her and she said that she would look at the coupon at the first window. I drove to the first window and handed her the coupon and she stated that I could not use it, due to the fact that "she didn't have a button on the register for it" . I explained to to her that I just received the coupon in todays paper and she told me again the same thing about not having a key on her register. I then took my coupon back and told her to delete my order and left.
