Bill Gates confessed he memorized license plates to keep tabs on staffers

Bill Gates once had a habit of memorizing his employees’ license plate numbers to keep tabs on when they came and left during the early days of Microsoft

As a guest on BBC Radio 4's Desert Island Discs show, Gates discussed various topics including his philanthropy work, career, personal life and the playlist he would make if he got stuck on a desert island (he's into U2 and the Hamilton soundtrack). But perhaps the most interesting nugget was how "fanatical" he was about the company — so much so that he secretly tracked employees to learn how many hours they were putting in.
