I had an issue with an Uber Pool ride a few days back. The PAX requested a Pool ride but had 4 passengers. In the spirit of the X/XL directive I took the PAX to their destination and sent a note to Uber that I had an issue with the fare. Uber's response floored me: In cases such as these please kindly ask the passenger to cancel and re-request an X ride. That is the exact opposite from the directive of going from an X to an XL ride. Horrible answer by Uber!
