I am normally very skeptic of Uber's guarantees, so much so that I totally ignore them. Their is normally so much fine print that it's not worth the hassle to track and monitor it. I just drive and hope I end the week with a decent number. Well I looked at today's statement and Uber is paying me a total of $350.00 extra. $44 is because of their application screw up (was down for awhile on Friday night I believe) and then an extra $306 for the $40.00 per hour promotion. As stated above in the title, this was totally unexpected. Good Job Uber for this nice surprise.
