Yeh, the dreaded “TEOTWAWKI“. *meh* It could be as simple an ending as NO MORE COFFEE!!!
While that may seem a simple thing, it’s really much, much worse than a Zombie Apocalypse or Nuclear Winter, either of which can be handily survived with the application of enough COFFEE!! (Well, and beer, but I’m not going there right now.)
So, several BIG freezers paired with an adequate power generation method is a must. Oh, and loads and loads and loads (and LOADS) of coffee beans in vacuum sealed bags (with oxygen absorbers included).
