At first I thought this pax was just rude or mental. But after I had canceled and got the fee, a call came in with the 415 prefix associated with Uber. He identified himself as Preston Scott ID number blah blah blah, a high level supervisor from Uber. After I'd finished laughing I hung up. I assume he would have gone on to ask for login details, password, etc, and then cashed out my week's money.
Then he requested again so I accepted and waited out the cancel fee. No idea who's paying but they ended up $8 in the hole.
