Five cars on the train. One agent in each car, hiding amongst the drab commuters. The public address system murmurs.

Please stand clear of the doors!

There’s a gentleman in a pinstripe suit standing in the doorway on Car #3. The doors close, partway, and reopen. A light flashes twice; a safety mechanism offers a pleasant chime.

The doors close, partway, and reopen. A woman with a rolling tote bag stands nonchalantly in the doorway of the first car, adjusting her bra strap.

The crewmen usher her inside and draw their attention toward Car #5, where a pierced-nosed hipster sends a text message from the doorway.

The hipster looks up. The train is now exactly five minutes late. Perfect. He steps inside.
