One of the great things about Uber has always been that you don't need cash. Cars cleaner than cabs. Drivers much nicer than cabs. The technology works. Etc.
I was just reading an angry rant by an ex uber driver complaining about how people don't tip him. The guy seemed a bit nuts. But it got me thinking. Do uber drivers expect a tip? Who doesn't like extra money I am sure. But really I love not dealing with cash and having to figure out a tip when dealing with uber. But am I just stiffing people?
