McDonald’s complaint: Rude and did not get my requested order.

I drove up to this drive through on the outside lane at approximately 5:10 PM and after waiting about 4 minutes finally heard a voice say, Can I take your order? I asked for an Iced Coffee with caramel. I was then asked what size and ordered a large. I was asked if there was anything else and I replied no, that’s all. I could not hear what was said next and said so then was told to drive around. I was the fourth car waiting. When I got to the window I handed the young lady a $10 bill. She went to the woman at the register and they exchanged words. Then a third young lady at the window asked if I had ordered the 10 piece nuggets. I said no that all I had ordered was a large iced coffee-caramel. She then told me no one had taken my order and I would have to go into the drive up line. I told her I had done that and repeated the above to her. She again told me I had not placed and order because no one had taken my order and I asked if someone could just get me an iced coffee and she said No, we don’t have iced coffee! as I could see the machine through the window. She then dropped the bill into my hand, she did not even have the courtesy to give it back to me.
