FYI, Korea's not in SE Asia.

Exactly. South Korea is a first world nation and is not even close to being considered "SE Asia."
Why waste time trying to spend dollars when you can easily exchange your green cash for Korean Won??? Can you imagine if a "foreigner" came to you and wanted to buy something using Yen or Won? Would you be offended? I would. It is only fair to use the currency of the country you are visiting, regardless of how strong you think the currency of your home country is. Agreed? Good. Please don't make all of us look bad by demanding that foreigners accept USD.
