perhaps they were charging a group rate and didn't want the pax to see your sad pittance. they'd demand a discount because the ride didn't cost uber gas, time, or depreciation.
I have a question, I was doing the cinco de mayo thing last nite downtown when my Uber app started to act funny, this was after I had dropped off a group of pax. So I logged off & when I logged back on it said my account was in use on another device. I rebooted my phone signed out & back in, still had the same issue. I called Uber's wonderful India support team & they were no help. Basically I was wondering is this a flaw with the app? Has it happened to anyone else? could anyone hack it & get access to your account with there phone or other device?
