Five hours into his first day as a cab driver, Scott McKinney is already uncertain as to whether he will continue in the profession.

"I was pretty happy to get the job, given the recession," McKinney admits. "But I never realized how many private struggles cabbies go through. When exactly am I going to get to pee? I've been holding it all day."

McKinney hopes that he will get to a chance to use the bathroom soon, but isn't even sure where to go. "I could duck into a mall food court or something. But using public restrooms makes me anxious. My hands always smell like balloons afterwards. What am I going to do? This is the worst day of my life."
