Driving for Uber is a choice, I don’t understand the controversy? Go get a job at a regular taxi service and/or only use regular taxi service if you feel so strongly against Uber. As a driver you sign up to drive for a service where tips are not expected, so why am I taking a flat fee service and putting a tip on top of it? Like anything in the service industry a tip should be earned not expected.
I have an app, I type in where I want to go, it tells me how much the ride will cost and someone comes and picks me up. There is a picture w/description of driver and reviews, I appreciate that a lot more than a regular taxi service (which I have taken in the past and been scared by my non-English speaking drivers). I have used it in various cities to get around, few miles here or there it was convenient and cheap, even with surge pricing. If we had a really engaging driver we gave them a tip otherwise no I did not tip nor did I feel obligated to. If drivers don’t like that don’t drive for Uber.
