Uber's CEO Travis Kalanick got into an argument with an Uber driver in San Francisco on Super Bowl Sunday last month. The whole incident was recorded on video.

The driver knew who he was, and started complaining about how he hasn't made as much money since they dropped their prices. It ends with the CEO swearing at him, and telling him it's his fault.

The guy drives for Uber Black, meaning it's a nicer car that costs more. The CEO claims they never dropped the price for Uber Black. But according to Bloomberg.com, it cost $4.90 per mile in 2012, and now it's $3.75 a mile.
