I don't think it's about coffee per se. It's about a taste of home, which some people enjoy. maybe not your people, but actual human beings with their own tastes clearly do enjoy the stuff. Military rations have little tastes of mass marketed brands as well. eg, Tobasco. It's no sriracha, but I'm not going to judge the military for the choice of putting in some MREs.
Whenever I find myself judging people or organizations after having only observed them from a safe distance, whatever my judgement says obviously has more to do with me, than with them.
There is no accounting for taste, but there you go again
From the graphic, I was hoping for a story on graffiti at the Olympics.
