If it's espresso, then black. (Sorry, but French press isn't 'espresso' as someone suggested a few pages back. You can use espresso-roasted beans, but what really makes it espresso is the process, not the roast.)
If it's a good dark roast made in a French press, a stove-top cafetiere (these are the two methods I use at home) or even in a good drip maker, then I add some milk, NO sugar (half and half is too thick, seems to overpower too much of the coffee flavor.)
For lattes, I ask for the smallest cup they have (in Starbucks, you can ask for a 'short' drink even though it's not on the menu) and have them put an extra shot. No whipped cream. Ever.
If I need coffee and have no choice but to drink crappy coffee, then it's black. And I drink it fast so it doesn't cool off too much. Heat disguises the taste of bad coffee (the same way cold masks the taste of crappy beer.)
Turkish coffee (no sugar) is also quite divine. But that's more of an after-meal kind of thing, not for mornings. I need to wrap myself around a big steaming mug of coffee in the mornings. And once I finish that one, I wrap myself around a second.
Sugar in coffee is an anathema to me. I'll literally spit it out of my mouth. I also don't do flavors, or flavor shots, or spiced anything. And if you have never seen it, you should watch Dennis Leary's coffee rant (NSFW!):
In a sense, I'm very non-fussy about my coffee (black, no sugar, most often with milk but can do without). But I am fussy about the quality of that coffee. I always grind my own beans at home, and now that I have a burr grinder, it's easier to grind just what I need, so I grind fresh every morning. I used to buy the Starbucks beans but then I discovered the Eight O'Clock Dark Italian Roast (not sure how widely that coffee is distributed. It's mostly an A&P thing, which is a US East Coast grocery store chain). A lot of people buy that brand and so the beans are often nice and fresh.
