Roll camera: a gleaming white basin inside a cubicle, an amber-tinted tile floor. Two seconds in, a young woman with a bob walks in, wearing brown leather platform boots. She turns around, raises her black leather skirt, pulls down her underwear, then squats. It takes about two minutes for her to finish her business and flush the toilet. She checks her makeup and walks out, oblivious to the fact that a hidden camera has just captured the entire proceeding.
