Yes, I'm that guy who turns that little vent for air before they seal the plane door before take off because it's uncomfortable on a plane. But one lady took it too far. She opened the emergency exit door next to her seat (over the wing) because she said it was getting stuffy! Luckily the plane was not in the air.
It happened aboard One Xiamen Airlines in China. She was arrested and will likely be fined. And she gets no pretzels aboard future flights!
