Option to tip please!!

All the app is missing is an option to tip your driver! No one carries cash anymore! And when Ive had something stuck in my teeth all night and my Uber driver had floss? I REALLY wanted to give him a $100 tip. But I couldnt. Because I had no cash and Uber doesnt let me tip thru the app on my credit card.
