In reference to the Chinese restaurant things, I've had similar experiences. I do know that Asian males are more likely to push the androgynous look, and some even go for straight out female. Heck, look at the anime 'pretty boys', they push gender appearance to a whole new limit sometimes. They go with the longer hair, or take a more feminine approach to clothing, or body structure. So in today's more modern world, androgynous is moving towards being pegged as 'male' in these countries. I think it's very cultural. And what's making it even harder is, as a PP mentioned, it's much easier for people of the same race to distinguish one another. I don't know many Americans who can tell the difference between Japanese, Chinese, Vietnamese or Korean people, but most Asians can in a heartbeat, at a glance. Then again, I live in the south now, where many people can't tell the difference between a relative and a possible date, either, but I digress...
