I don't remember. I think most fit in my wallet. Back then, the largest bill was the $10 equivalent, and I only went to the ATM every couple of months, so it was quite a few bills. I might have had an envelope?
Lots of talk about Korea in this thread. Many people know I lived there for 8 years and used to post on Jazzfanz while I was living there. I got to visit again this year in August for about a month which was super dope. I do remember getting handed huge envelopes of cash when I was paid for my job. I'd say that cash is still used more than in the US but, compared to what it used to be, cards are more widely used now. Also the largest bill is now 50,000 won, not 10,000.
I can really relate to Loggrad's experience in Germany. Living abroad (really living, completely immersed, not just visiting) more often than not, will change your perspective on many things.
