This garbage infuriates me. I regularly see them walk on with a suitcase and then a gigantic purse/duffle bag that will never fit under a seat as their "personal item." Some carriers will allow people with no carry-on to board first. I've seen people with those freaking gigantic bags walk over there and every time I see those douchebags put their stuff in the overhead bins. I've been tempted to pull that crap out and throw it in their lap - you forgot your personal item!
