McDonald’s complaint: Rudeness and Refused to take my order

I pulled up to the speaker to place my order when a female told me to pull up to the second window. I sat there and watched the car in front of me give her order and then get her order. When I pulled up to the window, the lady refused to open the window to take my order. I sat there for 20 minutes and watched 5 cars pull up behind me. When she finally opened the window, she asked me what my order was and I told her that I was told to pull up to the second window and I haven’t placed my order. She was rude and told me that she wasn’t taking my order because they didn’t take orders at that window that I would have to drive around again and place my order. I told her no, that I was told that my order was to be placed and I had a grandson waiting on something to eat at school. She said she wasn’t taking my order. So I drove off and went to another McDonalds and got my grandson something to eat.
