I love it, but there's one thing about it that I really wish would change. They are ever professional, graceful and polite in their interactions. Until I arrive at my destination, there's no place for me to escape to, and so I'm forced to withstand their rudeness. But I really wonder why I have to undergo such poor treatment. I believe that at least part of it has to do with our respective cultures - Japanese in general are simply raised to be more polite than Americans.
People here are often content to simply do their job and nothing more.
They don't go out of their way to do more than they have to, or to perform above expectations. Just doing the minimum is just fine for many here. On your flights, you get your food and drinks, and if you ask for a blanket, they'll give you one. They don't get paid to be nice. Not all Americans are like this, of course, but far more than I have seen in other countries, or from foreigners in America.
