A border guard in Bolivia once stamped my passport with an ‘Exit’ stamp when I was entering the country. As luck would have it, about three hundred meters after the border crossing I had to show my papers at a police checkpoint, where the cops immediately spotted the anomaly. To their credit, instead of making a big scene, they just had the bus driver’s assistant run back to the border with my passport to get the correct stamp.
Imagine how much fun I’d have had if no one had noticed and I later tried to leave the country with a passport that said I’d already left.
