McDonald’s complaint: Poor customer service

I visit this McDonald’s 3-4 times a week. This female employee Amy who is about 40ish and black has treated me bad every time I drive thru there and she’s working. Today as I drove through she was taking the money. I gave her a 100 and she said to my face oh my god a hundred. Got the manager back there and they went on about me staring at them and more stuff. She handed me my money and rolled her eyes. Normally she is at the window giving food and always gets mad when i ask for a straw etc. always throws my order to me. I took my change today and ask at the next window if that nice lady would mind getting me the manager. She did and I explained to her I am sick of it. I won’t take her attitude anymore. That she apparently hates her job and is the rudest person I’ve ever seen working in public. She put her head down and replied I’ll take care of it. She wasn’t happy herself you could tell. We al have bad days but not every single time! It made me so mad today! Something has to be done ! Because when I go back she won’t treat me like that ! I even told the manager if it does the cops will be involved because it will be a fight.
