@tsarstepan,
Hmm. I just read that story, and the upshot of it was Uber acknowledged from the get go that was some kind of mistake, and were working on adjusting it.
She was billed 50 some dollars for a fare, but contested it. Uber was going to credit her about 15 dollars, when she started getting emails about $12,000.
This Jaime woman was getting all kinds of hysterical in her emails, even though she later said she didn't fear she her credit card was going to be charged.
It's not like Uber was actually charging her $12,000.
In any event, she chose Uber instead of other transportation because she was afraid she was going to be late for her pub crawl. Couldn't risk missing a bar or two.
