P.S. "regular coffee"
P.S. The confusion this usage naturally conduces to reminds me of another well-established regional usage. In the New York City area but no place else on Earth that I know of, the term "regular coffee" is used not in opposition to decaf — as it is everywhere else in the English-speaking world — but to denote coffee with milk and no sugar. (That's right, milk — not cream.) Which seems like a pretty fucking stupid default position, since you can always add milk if it was omitted and the customer wanted it, but you can't take it out once it has been added.
But there you are. The usage exists and persists all the same.
