I remember when I was in South Korea, I went out to eat with some students, and one of them handed the chopsticks to cook on the hibachi grill to a female student and said 'something something yoja something something'. She smiled demurely and cooked. I knew 'yoja' meant woman, so I said, "Did you just say 'You are a woman, so you cook for us.'" and they said I must know Korean. I told them I just knew 'yoja' and guessed. The girl had smiled at the joke and cooked. I thought an American girl might scowl over that. Now, South Korea is heavily influenced by feminism and I would imagine women would be uptight about that.
I may be offended, especially if I have to pick up the dishes and wash them too simply because I am a woman? My feelings on this would also vary, depending on if I have help from other women, and the guys are doing something else like putting up the chairs/tables. If this was done in good fun, etc. I would not be offended to cook...however if there is a continuous trend to cook, clean, make the coffee, be the secretary instead of leading, etc. that could be a problem. And, this isn't feminism.
