This pretty much applies to all Asian people who are not Japanese, I've found. Koreans are the worst at this, there is absolutely no concept of which side to walk on over there, but they really need it with the number of walkers. If Korea ever hosts anything big/international again, bigger than the winter olympics in BFE, then they will probably move forward a tiny bit and run relentless 'cultural lifestyle education' videos, banners, and flyers everywhere, and some of it might soak in. They did this before the 2002 World Cup with regards to Koreans and their kimchi breath, and so brushing your teeth after meals became common around that time I think. (that also took off because it was a good excuse for company workers to take 1 hr lunch breaks, and then go brush their teeth in the bathroom for 30-45 minutes after lunch, thus not getting back to their chairs until 2) A few years ago they ran a 'wash your hands after you shit' campaign and I did notice that there was a little more hand soap available in restrooms. They had the G20 last year? A couple years ago? and they ran a shitload of ads for that too, the theme was 'Koreans, be friendly to whitey' - clips of a white guy marrying a Korean girl in traditional Korean style, a lost foreigner on the street asking a very friendly Korean girl for directions and her obliging, etc.
