People who stand up in aeroplanes even before the seat belt signs are off, then twat you with the bags they drag out of the overhead lockers. One of the best things about the covid debacle was only allowing passengers to stand up and deplane 2 rows at a time. Everyone got off quicker as well.
Been there a few times but not on a plane. Can imagine its interesting. Internal flights in Korea has people with chickens and cooking utensils. Luckily no cooking during the flight
