@Ahn Sarang: #4 reminded me of another kdrama specific thing
5. Weightlifting fairy - In Kdramas you always see everyone taking big bites and literally stuffing their cheeks like a hamster (even women have round cheeks full of food) and often talking at the same time ^^; That's not table manners where I come from (its more like taking small bites, chewing and swallowing before talking etc)
Moreover, it's not the "even" women, I would say female characters do it more often than male characters. Usually, it's to show that she's not like the other girls, so special
Aso, big eaters may be there for a comedy effect. Not the way they eat, but the amount they eat. Like, a girl takes 5 portions and call it a snack
