A receptionist dressed in a Willy Wonka purple velvet suit sits at his desk in a richly appointed mahogany trimmed office.
As customers approach from the southern entrance, he sees them, facing west. This is possible because of a wall to wall and floor to ceiling mirror placed at a 45-degree angle between himself and customers.
Another man sits in an alcove behind a curtain, watching both receptionist and customers on a video monitor.
The man who set up the monitor, curtain, and mirror is long gone, but used to work repairing old arcade games.
