A Japanese company is testing a prototype drone in Tokyo that they hope will help combat the country’s burgeoning overtime crisis. The developers say it will encourage employees to clock off early by blasting Auld Lang Syne – a song commonly used in Japan to indicate the closing time. But at a cost of ¥50,000 ($443) per month for service, some might hope for a choice in music or maybe even noise reduction headphones to dull the constant drone in the office.
