I cannot stop laughing at this picture, and the title is really the punchline of the joke here. I imagine someone just walking into an abandoned building and someone just being there. "This reception: take a number and have a seat 'till we call your number." The sheer surprise either scares the person into the flight or flight response and they decide to pick up a brick and just chuck it at the windows. Perhaps instead person says, "No, I'm gonna explore!" and decides to chuck bricks at the windows. I really think I got the wrong message from this, but you cannot imagine how I am dying of laughter right now.
