Had an idea for a movie.
The premise is that for one day all coffee in the United States DISAPPEARS.
Productivity will grind to a halt. Commuters will slowly bump into each other holding suddenly empty travel mugs. They'll look at each like, "Never mind hitting my car, WHERE IS MY COFFEE?" Misspellings will QUADRUPLE. Meetings take even longer. Coffee shops everywhere will look like the zombie apocalypse with people lethargically meandering around them in and out like the undead that they are.
I call it, "A Day Without Colombian".
