The last time I rode the Orange bus on a Saturday – same bus stop, same time – it was 15 minutes late. So I thought there was no harm in now showing up 10 minutes late and still catching it, but it would appear that I missed it. Shucks.
And one time, I was catching the purple bus, and I again banked on a secure 10 minute cushion. So I showed up just about 3 minutes late to the stop. As I walked up, the bus pulled up from the other direction! I had to run to make it to the stop in time. And then, I actually delayed the bus further because I hadn’t had a chance to count out my change. I had to do it while the bus was waiting on me, and my $1-bills all disappeared at the crucial moment.
Update: I ended up catching the bus a bit later in the afternoon. Same bus, same stop. I got to the stop 3 minutes late, and the bus came 2 minutes after that. Wow!
