Your bank may deem that a series of credit card payments to Uber smell of fraud.

This means that the next day you will be unable to run your credit card with Uber until you call the bank. I hope you don't have to go anywhere before 8AM! This happened to me today. As dumb luck would have it, a coworker lives in my apartment building and he gave me a ride to work as otherwise I would have been marooned until 8AM.
