How my shift at McDonald's went

So this lady orders her food and I tell her how much it is. She pulls up to the window and pays me. I give her, her change and tell her to have a good day

Karen: Where's my food?

Me: Oh you have to pull up to the next-

Karen: No where is my fucking food? I gave you money, Where's my fucking food!

Me: Ma'am you have to pull up to the next window

Karen: I ain't pulling up to shit! Get me my motherfucking food!

Me: Ma'am your food is at the next window

Karen: Get me your higher up! Now!

So I get my boss, who is Latina and before she even gets a word out.

Karen: Do you have a boss who speaks English?

Boss: I speak English

Karen: * eye roll and complains about the same thing*

Boss : Your food is at the next window. Just pull her.

Karen*saying every curse word ever and calling us names*

At that point my boss walks to the next window, gets her food, hands it to her and says "Hear now leave!"

Karen: I'm never coming back here again

Boss: *mutters* Fucking bitch

You haven't met stupid until you've worked in fast food.
