Koreans will skip you in line but aren't as pushy as Chinese.

I have been skipped in lined by Koreans but Chinese will literally push you out the way. In the week I spent in China, I was pushed and hit (mostly by older ladies) than I ever was in the six months in Korea.

after one day in China I learned if you ain't pushing you will be waiting on that next bus, train, taxi or whatever. I'm 6'2" 270lb I was built for being pushy in that country!
