How stupid can you feel when you pull up to the urinal for the first time of the work day, and you realize that you have just spent the last 3 hours with your fly down?
Speaking from experience, it's pretty dumb. Your mind quickly races through everywhere you've been and how many people you've seen. For me, I spent half of it in my car by myself, but there was that stop for gas. Damn! It was busy, too. Maybe 20 people, tops?
