Pattern recognition.

It's a near-inevitability that whenever I go into a coffee shop, I bring in a line. I don't mean I make a line; I mean I come into a place and there's maybe two or three people ahead of me at most, and after I've placed my order I'll look around and see there's now a line out to the door. Not every time, but often enough I'm not quite surprised by it anymore. It happened again today, and as much as I know it was my luck to get into the place just as nearby schools were letting out for the day, I also know it's just what happens.

Now, if I just had some idea how to properly monetize this.
