Ask a Cop? No, push a button.

There are several NY City policemen throughout the subway stations. I have been so tempted to use them as information booths, but I have resisted because that's not their job. I have, however, discovered that there are these buttons you can push that gets you a real live subway smart person! You just say something like, "Uh, yeah, I want to go to so and so." And the human voice on the other end assures you that there is a way if you follow their instructions. If they would only provide someone to read you a bedtime story and tuck you in. . .
