Taxi driver's attitude problems are the main reason why I wish uber would take over. I was in Vegas recently and got a taxi to take me ~0.8 miles. He was so sarcastic about how he was happy for me that it's such a short trip. I don't need any of that attitude when I hop in a a car. I have almost always had pleasant conversations with my uber drivers. Customer service is so important and it seems like uber got it right.
My pet peeve is when drivers try to tell me that their machine to process credit cards is broken and I need to pay in cash (so that they can avoid a payment processing fee). When I respond that I don't have any cash and that they're just going to have to give me the ride for free, miraculously they are able to resolve the problem and take my card...
