There are two policemen on duty in Sofia, when they're approached by a tourist. He asks a question in English, obviously looking for help. They don't understand him, so he tries again in French. Still no better. He tries once more in German, and, getting no response, finally gives up and goes away.
"I think we should learn a foreign language, don't you?", says one policeman. "It might be useful". "I don't see why", says the other. "That tourist knew several, and it didn't help him."
