I used to work in the basements, backyards, airways, streets and rooftops of Harlem, Washington Heights and the South Bronx so I often loved being called to a XNNCJEQ. It meant I’d be dry in the rain, warm in the winter, cool in the summer, could sit down and most of all....KPNN YLESCR!!!
Excepting those benefits, the author is correct.
I remember in the Army in Germany, we had an ad hoc “class” on vehicle maintenance in the middle of winter on the hardstand (parking lot) during a snowstorm. The grizzled old sergeant delivering the “class” at the colonel’s “request” just stood there swearing and saying it was the stupidest thing he had ever seen in his Army career, which encompassed the Kasserine Pass and obviously had seen more than his share of misadventures.
