From working at McDonald's I've seen the entire stupid spectrum. My favorite experience was one day when I was taking cash and orders in the drive thru. On one of the screens is all of the orders and usually the one at the top is for the car at the window. So a lady came up to the window talking on the phone. I asked her if she had "this order" to make sure she got the right food. It was some snobby woman in a nice Lexus. She said "Yea whatever" and just handed me her card. Well, guess what? She got the wrong order. Not because it was my fault, but because she didn't care to listen when I asked if the order I had on screen was hers. In a couple of minutes I was requested to the front counter by none other than that woman. She was very upset, saying "You messed up my order," or "A manager should know what they're doing." I told her we would refund the order and remake it but she didn't care. She was more interested in trying to make me feel dumb because I was a fast food manager. She kept talking about driving a Lexus as if it was for the elite. After a minute of her ranting about how stupid fast food employees are I finally just said: "Shut up and get out of here." She was taken aback, she said "I'll be back, and I'm gonna speak with someone higher and you'll be fired." I just laughed at her. Really though, if someone is disruptive in the restaurant a manager is legally obligated to tell them to leave. Not ask them, tell them. I was 17 at the time anyways, I didn't care if I was fired. But damn was satisfying to tell that bitch to shut up mid-sentence.
