Exams on Saturday were the worst because the school and the transit system wouldn't communicate. Usually we had buses running every 6 minutes to the university. Saturdays it was once an hour. Must have been like 300 people waiting for the bus when I got there. A few of us jumped in a cab and were going to split the cost but right before we left a random guy asked to share with us as well. When we got up there he paid for the whole ride.
