I can handle interacting with foreign people. Most of them are quite fluent in English. At the most I have to read their requests and complaints twice. And when they ARE complaining, they're almost always still nice/polite about it.
Explain to me why I'm encountering Japanese folks that probably don't speak a bit of our language, and yet, I don't have to read their tickets 17 times. As opposed to the schoolteacher from Indiana who types like a three-year-old on crack.
