The Unreachable Star

Took on a pax this morning and a couple minutes into the ride I get a nice "exclusive" ride offer for a reservation. Struck me as odd since I still had over 20 minutes to the current pax destination. But I figured Uber had it figured out ok. As soon as I accepted, Uber started pestering me how I was going to be late for the reservation, might lose the fare, etc... And sure enough the reservation rider canceled because I'd gone past the reservation time just before I dropped off my pax, at which point I was still 20 minutes away. WTH, Uber? I didn't think I'd have to scrutinize the offer to see if it was even humanly *possible*. There wasn't any traffic or delays on my way. My first time with this kind of silliness. Anyone else? Hopefully this doesn't affect my "reservation karma" since it was the pax who canceled and not Uber kicking me off the ride.
