I've gotten a couple emails now, but it's pretty frustrating because cancelling usually isn't my fault. Usually the rider is taking forever and waisting my time or i can't f'n find them because they put the wrong location. Another time I accepted a request, was driving to the rider, some idiot driver cut me off so I honked at him. Stuck in traffic in Santa Monica, he gets out all pissed off and throws his coffee at my windshield. I had to cancel and go get a car wash to even continue driving. Other times, riders keep cancelling once I accept their ride, does that count toward our cancellations too?? Uber sucks ass.
