I took an Uber from the airport into downtown to the hotel i was staying at. My driver did a good job of navigating through some really difficult rain showers and thunderstorms and got me to my destination safely. At the conclusion of the ride I had sensed that he was hoping/expecting some kind of tip. He has a sign inside his car soliciting for tips too! However I know with Uber you are not required to tip and I did not feel obligated to. I didn't like the sour look he gave me after I thanked him for the ride and parted ways. Thanks for the ride! =Þ
