This is a small oddity from our recent trip to Seoul uncovered while doing our accounts. The receipt of the restaurant we went to the night before our ill-fated trip to the British Embassy has the following information:
내국인 (native persons - i.e. Koreans, 2)
외국인 (foreigners - 0)
I don't think I'm suddenly being mistaken for a Korean, even if it was dark in there, but I find there's something slightly unnerving about the idea that people are watching and keeping count of racial differences in this way. Perhaps it says a lot about Korea that anyone thought this could be done in the first place - back home it's sufficiently multicultural that it's impossible to tell on sight who was born in Britain and who wasn't.
