I was in the kitchen in work making myself a cup of tea and there was someone else in there, making a cup of cocoa. Before adding the water, he added a spoon of coffee. I've been drinking cocoa and coffee mixed together for years (when I used to work for a chemical company, the canteen had a free drinks machine and I used to get a cup each of cocoa and coffee and mix them together). I was surprised to see someone else doing this so I mention that I do that as well. We were both glad to find someone else who drinks "poor man's mocha".
