This is getting to be known as one of the 2 ways that riders can rip us off. I've heard of this happening from Former Uber Drivers. They don't even have to give you cash, all they have to do is SAY they gave you cash and if the CSR beleives them, they get the ride for free and you get cheated out of it. The other method is for the passenger to cancel the trip after they get into your car. This one is infinitely worse because they can simply say you have the wrong passenger, and if ANYTHING happens on this trip... James rivers insurance doesn't cover ANYTHING at all, because you arn't on a trip.
