Just for clarity. I agree that urgent publishing fee does not make sense. However, there are 1-2 case/year in my editor work (open access, VERY reputable hournal) when I got a manuscript from the publisher, send to the reviewer and get their response in less than 24 hours. Unfortunately (for the authors), such a rapid response is usually REJECT, for plagiarism or complete lack of novelty. I have never seen a paper accepted in less than 2-3 weeks (on Communication journals).
