Never Listens, Problem Solved Anyway

I’m having a coffee in a mostly empty ice cream shop when I need to use the restroom. A woman is leaning against the wall next to the restroom door, doing something on her phone. I don’t want to try the door in case she was waiting for it, so I approach her.

Me: “Excuse me, but are you in line for the restroom?”

Woman: “I don’t work here.”

Me: *Genuinely confused* “I didn’t ask if you worked here. I’m asking if you’re wai—”

Woman: “I SAID I DON’T WORK HERE!”

With that, she stormed off, so I tried the restroom door. It was vacant.
