I agree Kramer. To me the surprise is not the juxtaposition of the man sleeping on the pavement within close proximity to the line up of JWs. How do we know that the JWs have not given the man food or talked to him? A photo can be very misleading - it's a single snapshot in time - not an extended recording of everything that was or was not done.
Back to what surprised me: The lineup of five - count five! - JWs staffing a single immediate location. Even if I were a potentially interested passerby, I'd think twice before stopping to show any interest with such a big lineup. Whatever happened to two Witnesses per cart?
