“Waiting room” is the 5x5m space with only one entrance. First, a viewer chooses the thing he/she expects on the reception. The viewer can enter the “Waiting Room” only through the terminal. If there is somebody inside, entrance is blocked. There is a chair and a screen inside, it shows the looped video of endless processes. At the entrance, there are sensors that allow to fix when the viewer enters or leaves the room. After the viewer left, the video turns off and another person can come in.
