Sounds tasty. Not!
A couple the wife and I used to bang

would make their coffee with one of those old percolators and there were always grains floating around on my damned coffee. Very troublesome that a refined gentleman such as myself would have to drink coffee grounds. It's just a good thing that chick gave great head or the coffee would have pushed me over the edge.
In the army, when we were in the field, we'd mix some water with a coffee packet and a cocoa packet in our canteen cups. Yum. It's akin to having a flavored Latte' in the bush.
