Stop the presses: Uber CEO Travis Kalanick is kind of an asshole. This isn't news to either his own employees internally, or to his contractors, those who currently drive his whole operation, helping him bolster his company up to be one of the most valuable startups in the world.

But the latest piece of evidence is pretty damning: A video obtained and transcribed by Bloomberg, where Kalanick argues with his Uber driver.

When the driver, Fawzi Kamel, asked Kalanick about the price dropping on Uber, the CEO replied, "Bullshit."

“We started with $20," Kamel responded.

"Bullshit," Kalanick repeated.

It's an aggressive style all too familiar to the people of Silicon Valley, the programmers who work for him, the venture capitalists who invest in him, and the tech enthusiasts who read the cover stories on him. But now, it's starting to get more mainstream coverage thanks to the rise of the #DeleteUber movement.

The conversation ended (at 5:49 in the video) with Kalanick lamenting to the driver (after not answering the driver's point-by-point critique of Uber):

“Some people don't like to take responsibility for their own shit. They blame everything in their life on somebody else. Good luck!”

The best of it starts at 5:49:

Per Bloomberg's Eric Newcomer's reporting, we know Kamel gave Kalanick one star.

The driver gave Travis one star drag himmm https://t.co/Tpxpq7Q38P — Emma Hinchliffe (@_emmahinchliffe) February 28, 2017

We reached out to Uber on Kalanick's Uber rating but have yet to hear back.
