It's all a conspiracy

It never occurred to Bob, the man sitting beneath the poster that people were looking at him weirdly. Never once did it cross his mind that someone, somewhere we're testing the well-known theory that everyone has their counterpart out in the world, and that this someone was an artist. An artist who deliberately knew about his habits, routines but most and foremost itineraries and wanted to play the infamous I-poster-you-when-you-least-expect-it prank. Oh no. This was no coincidence, dear Bob. Not at all.
