It's funny how there is so much social stigma around the use of a foreign money.

I wonder if it is singularly an American or Western thing (we are pretty weird about money in general: people don't like to be asked how much they have, how much they make, how much things cost, etc) or if it's like coming up to people and trying to speak at them in a made up language like Esperanto or something.

This would be something really interesting to look into.
