Quite annoying

@Red, just don't know if living in a very remote village in her native country has something to do with her manners.
@Karie, if we're the only ones inside the dining room. But most of the times, the female eaters on those times are only 3. Most times there are 7 men aound the place.

@Alex, I just can't tell her that. She deliberately wants to finish her meal early so she could take a nap in the locker room. My only option is to change my break time. But I'm working till late in the night and having my lunch at 1 is just the right time. If it comes to be unbearable I might change it to 1:30, though it's quite a time away from my last meal.
@Cat, if I look at my left, I'd see the window but it's still closed as it's still freezing here. If I turn my head to the right I'd see a lot of men ranging from 30's to 60's. Those are Japanese men. If I keep looking at my right, they might think I want to hook up with one of them. This is Japan. And probably not only in Japan. If a beautiful woman like me keeps on looking to the men's side and most have finished their meals too and watching TV, napping or simply idling while they're just newly energized with the state of the art packed lunch in lacquered boxes, something might snapped and I might probably bid goodbye to CS forever.
It's a dilemma. I opted to bear with it in silence. She's quite rude on other things too. I just don't want to pit rude with another rudeness. Maybe it's OK in their culture since I had worked with another Chinese in another factory and she did that too. Anyway, Friends, thanks for sharing your point of views. It's lightening. Have a happy weekend everyone.
