It depends on what the coffee is. At home, I have a real dark roast coffee, so mostly I drink that coffee black. At work, I have two choices: A lighter roast, so I add a little bit of cream, and a pinch of sugar -- or the instant coffee sludge, which mostly consists of Equal and french vanilla creamer.
I don't want to come across as one of those Americans who drinks tea just to be a hipster, but I really do prefer tea over coffee. I haven't cared for the taste or the acidic nature of it. I do love a latte now and again, though - give me a blackberry or a caramel latte and I'm in heaven. Hell, I'll even drink those insanely sugary gas station "cappucinos" every now and again.
But as far as tea goes, just plain tea, no sugar or milk. I'll sometimes add a little bit of honey, but that's pretty rare. I'm mostly fond of regular ol' black and green teas, but my favorite of all time was Lipton's Honey and Lemon tea. Ohhhh man, that was the stuff.
I'm not a fan of coffee. But whenever I get some forced on me I take it black. Milk or Sugar just makes it taste worse and lessens the kick, which is the only enjoyable part of it. Never tried cream, but I don't actually like cream, so I think it's a safe bet that I don't want anything to do with that.
If you don't drink your coffee black then you don't like coffee.
Just like how if I put ketchup on my fries I don't like fries?, or if I eat oatmeal with some honey I don't like oatmeal?, or if I like blue cheese with my wings I don't like wings? I always find it pretentious when people are like "OMFG YOU PUT CREAM IN YOUR COFFEE".
This, who the fuck cares how you take it. Most people drink coffee for the effect not the taste.
