Waiting time

Dreamt that I was in the food court at a train station/mall eating a rice ball.  As soon as I got settled with my snack and my sauce, a homeless man sat with me and would not stop talking.  I couldn't think of a way to politely tell him to shut up, so I decided to tell him that I had to leave for my train.  Turns out, it was in fact train time, so I started hustling through the mall part of the train station when I realized I had to pee.  There wasn't any time to do so in the nice, mall bathrooms, so I was going to have to take my chances on the train.
