Diner where the coffee never stops steaming

I'm sitting at the counter and the coffee in front of me never cools, not once, even though I keep drinking it. The waitress knows my order before I say it, and every other booth is filled with people who nod at me like we've known each other for years — but I can't place a single face. I keep thinking I should ask someone a question, but I never do. Just sitting there, warm cup, hum of the fridge, that's the whole dream.
