1 less reason to die
... because good coffee is that important.
The poster actually reads "1 less reason to Diet", but I read it as "die" when I first saw it, and decided to photograph it that way.
Of course, the worst coffee I ever had was at a particular army camp. It was the kind of coffee that indeed made you wish you were dead - unlike, apparently, good old Nescafe, which gives you a reason to live. I'm more of a tea person myself, favouring a pot of Earl Grey ("Tea. Earl Grey. Hot", et cetera) on occasion.
