The door camera warned the courier that it was recording a video. The guy responded to this by dancing.
The courier from the video, instead of a standard delivery, showed the owners of the house he came to a personal dance number. The automated video surveillance system became the unwitting director of a spontaneous performance.
At first confused by the official computer voice that announced the video recording, the courier quickly overcame the initial shock and decided that since he was on stage, the performance should be unforgettable. A few awkward but sincere dance moves raised the mood not only of the recipients of the order, but also of thousands of social media users.
