Traffic Control in Korean Restrooms

Can't resist blogging this from my cousin's Olympic blog:

"That gives us just enough time to hit the restrooms. I don't think I've mentioned them so far, but they are worthy of mention. Korea is one of the most technologically based countries on Earth so I guess that it is no surprise that the toilets have more buttons on them that seem possible. But did you know that they have a sort of air traffic control board in the front of the restroom? A video monitor shows you which stalls are open and whether each stall has a western style toilet or a traditional "squat" toilet. I can't speak for the women, but I notice that the men don't pay any attention to the video board and will often stand waiting at a closed door when the board says that there are clearly open stalls. The other interesting thing is that the women who clean the restrooms don't give you any advanced warning when they go in to clean, they just barge in."
