This would explain the mass amount of people staring at you, with cameras watching your every move.
You don't exactly like working here. And throughout the time, although you haven't said it, this 'glorious leader' business seems overworked. Not a lot of people have good living conditions and everywhere has his annoying face.

You could throw your flashlight at it and run. Although, that wouldn't exactly work well in your favor, because you'd probably die.
