The worst are the authors who reply "Those dates are unimportant." And then I have to reply "It is journal style to include the dates of data analysis. If ALL queries are not answered the article will NOT move forward in the publication process. Please provide ALL information requested RIGHT AWAY."
Sometimes I wish I could just be totally honest with them. "Dear Dr. BusyMan, I know this is annoying to you; it is annoying to me also. Personally, I don't give a ripe crap about the data. Unfortunately, telling me it's irrelevant doesn't make it go away. I'm being paid to do a job that specifically includes hounding you for specific information, and since I care more about keeping my paycheck and not getting yelled at by my boss than I care about your comfort and good regard, I will keep pestering the living daylights out of you for this irrelevant piece of data until you freaking give it to me. I am the unmoving object between you and finally getting this damned paper published; I am the Sphinx on your path; solve my simple riddle and you may pass. Just do the thing so we can move this along and never have to deal with it, or each other, again. Best Regards, The Editor"
