I happened to be next to a store in Central Mexico when an armored cash pickup truck showed up. It was a MUCH more intense scene than the pickups I've seen in the states. There were multiple guards in the parking lot, guns drawn, that looked very alert; they weren't just going through the motions.

Nothing happened and the stop was done in a couple minutes, but it reminded me of how different the daily lives of those guards must be from any job I've ever worked.
