It's been a pretty awful year for Uber, the ridesharing behemoth so obsessed with undercutting the prices of its competitors that it allegedly forgot to do things like make sure its employees weren't ruthlessly and horrifically sexually harassing female engineers and threatening them with termination when they had the audacity to report it. Even though it's expensive and dangerous to drive for Uber, the company is going out of its way to bury drivers' efforts to unionize. Over the past month, the #deleteUber movement has caused the company to hemorrhage nearly a quarter-million users, and at this rate, it's easy to understand why.

The Uber Killer: The Real Story of One Night of Terror On a Saturday in February, Jason Dalton got into his car and began shooting people.

The stress appears to be getting through to Uber CEO Travis Kalanick, if the video of a recent conversation between him and a San Fransisco-area Uber driver is any indication. Bloomberg Tech has the clip of an exchange between Kalanick and Fawzi Kamel during an Uber Black ride in Kamel's car on Super Bowl Sunday. Kalanick's boasts to his female friends about the tight ship he runs kind of backfires when Kamel calls him out on, among other things, Uber's plummeting prices, which the company uses to bury competition at the expense—literally—of the men and women like Kamel who drive their cars. Bloomberg has the full transcript of their exchange, which gets grim pretty fast.

KAMEL: I lost $97,000 because of you. I'm bankrupt because of you. Yes, yes, yes. You keep changing every day. You keep changing every day.

KALANICK: Hold on a second, what have I changed about Black? What have I changed?

KAMEL: You changed the whole business. You dropped the prices.

KALANICK: On Black?

KAMEL: Yes, you did.

KALANIC: Bullshit.

Note: This is not bullshit. As Business Insider notes, Uber Black's prices have fallen steadily in San Fransisco over the past five years, and today, Black drivers "get paid less and their business faces far more competition from other Uber services."

KAMEL: We started with $20.

KALANICK: Bullshit.

KAMEL: We started with $20. How much is the mile now, $2.75?

Once Kamel broke out the receipts, Kalanick evidently decided that the time for reasonable adult conversation was over.

KALANICK: You know what?

KAMEL: What?

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

An Ayn Rand-humping billionaire technocrat—yeah, he denied his Atlas Shrugged fanboyism later, which, okay buddy—ending a legitimate debate with one of his hundreds of thousands of drivers by cursing the guy out and telling him that his bankruptcy is his own fault is a very bad look. If you didn't already #deleteUber, maybe this will have you thinking about giving some other ridesharing app a shot.
