And then the mayor of the town shows up out of the blue and says no, this direction is going to have a longer wait, I'm going to delay people intentionally, so that when they're stuck in traffic, sitting there, they'll have more of a chance to see signs/placards of, and contemplate patronizing, nearby businesses, whose owners are my political backers. That made a big impression on me... must have, because I feel like I've told that story in an HN comment before... but anyway... yep.
