How Not To Behave on an Elevator

I thought elevator etiquette was pretty well-established at this point in time. Not so, as I found out this morning.

I got on an elevator. Then a woman joined me. But instead of pressing her button and facing the door, she pressed the button and faced me. She was about three feet from me, looking directly at my face, holding a cup of coffee underneath her chin. She was wearing a beret. I think that has to be known. Because she was facing and staring at me, I assumed she wanted to say something. I removed my headphones, and gave her the "Let's not make this awkward," nod. She didn't process it and continued to stare and say nothing. After about four more tense seconds, she lifted the coffee cup to her lips and started slurping what had spilled onto the lid. But not a regular slurp. It sounded like an alien learning to drink, REALLY loud and cartoonish, while spinning the cup around like an electric can opener. When she finished being a lunatic, she looked back at me and said, "Have a good rest of your day." Then, no exaggeration, she skipped off the elevator.
