I once had a seatmate pull out nailpolish and REMOVER, and start to remove her old polish on AC. I immediately got up and tattled on her, and the FA raced over to tell her she was an idiot. (or words to that effect)

Unfortunately this was at the start of a 5 hour flight, so it wasn't too comfortable sitting next to her for the duration of the flight....


Over brunch this week a friend told me that he was seated between two nose pickers apparently having a contest on his AC flight this week.
