Yes, I also find it hilarious (in any culture) when someone is critical of a foreign speaker. Then when that person speaks a foreign language, usually their accent and style is so predictably awful that people are hiding under their desks. That is why I made the joke about asking natives: "So, how is your Thai... or German?" Those two languages are pretty rare to hear in Japan, especially for non-native speakers. It acts as the perfect monkeywrench in their gears.

    > My wife points out when I make mistakes in Japanese, but I ask her to do so. If a coworker or stranger were to do so, it would be embarrassing, and that's the difference that matters.

Another great point. In my experience, the very best language lessons are from casual interactions when a stranger makes a correction to my foreign language when replying me, but not in a derogatory manner. Most of the time, you can tell they are trying to be subtle and give you a helpful hint.
