Can't stand the following:
DB's not waiting their turn to de-plane.
DB's who lean their seat back.
DB's who don't sit in their assigned seat.
DB's who put their bags over someone else's seat.
DB's who can't seem to hit the toilet with anything.
DB's who don't turn down the sound on their devices.
DB's who rush the counter while boarding even though they are in group 6.
DB's who walk right down the middle of the hallways in the airport.
DB's who get a wheelchair and obviously don't need it.
DB's who take up two stools at the bar when it is crowded.
