bad coffee

Bad coffee? PO3 Steven Sherrill. I didn't drink coffee until after I enlisted in 1974. I drank mess hall provided coffee to stay warm on cold guard duty nights.
The coffee in c-rations was interesting to say the least.
Later I learned to drink coffee from post that were never cleaned with the thickest coffee at the bottom - high test with coffee solids :-)

"Bad coffee?" Does not compute.

One hour old coffee, one day old coffee, one week old coffee, coffee of indeterminate age, it didn't matter as long as it was hot.
