Mcdonald's - Lancaster

Okay, once after a midnight lesson. After a long night of worship in Victory Hill, my daughters and I stop at McDonald's to order a salad for my men's lunch the next day and a vanilla ice cream coffee for my daughter. After waiting for two children on the ride to order my food, I asked the lady behind the microphone for a medal. Vanilla ice cream coffee. Then she tells me I can go ahead with my order. I thought she didn't hear me, I repeated the order. Then she doesn't tell me that she heard I repeat my order. I waited and then I said hello. Then she tells me that I have a good night, and that she won't take my order and wanted to turn off the microphone. Shocked and confused, I went straight to the window. When I got there, she turned the window on me and told me that she won't take my order and that I had to go. I stayed there because I didn't know what to do and was so confused. I tried to get the attention of the other workers, but they wouldn't answer me. The crazy lady then tells me through the closed window that I have to go, or she'll call the police. Can anyone explain this to me? Still in shock and Awe! I'm mother and grandmother. I've never been embarrassed!
