I had a passenger today that was kind of a pain in the ass - crappy attitude, placed pin in wrong location. She had this permanent stank face to her, if you know what I mean. So after picking her up, she tried to negotiate an offline, cash only future ride to the airport. Since she already got off on the wrong foot, I declined. Wouldn't be surprised if she rated me poorly. I am now thinking about reporting her for disciplinary action and to preemptively remove a possible bad rating. Had she been nice about it, I would have actually considered it. With her attitude, however, I would be concerned with the possibility of her scamming me and not having cash at all (not to also mention the lack of insurance). What would you guys do in this situation?
