Sudden Unintelligence Incident

I just experienced someone having one of what P.J. O'Rourke famously termed an SUI, or "Sudden Unintelligence Incident".

Basically, a person who shall remain unnamed used a program I wrote to make a request for something.  And this person clicked an option by mistake that caused the request to be formatted incorrectly, so the person did not get what the person asked for. 

I carefully explained why the person did not get what the person asked for.  I included the section of code that governed what this person had done and explained it in some detail. And I even said that I would fulfill the request as the person had expected it to be made (and I did), but that the person needed to be sure to click the correct option next time for this particular use case.

Then this person had the gall to tell me that my program was broken and that this person had, in fact, clicked the correct option, and that I needed to test it and I would see that it was broken.

Which was a truly stupid thing to do, because, naturally, I did immediately test it, and it worked exactly as described.  Analysis, après O'Rourke:  Yes, the dumb bugger clicked the wrong button instead of the right button for this particular use case.

Now I'm waiting for this person to complain to my boss that I am a meanie.  I certainly hope this person includes the email I sent explaining what this person did and why it produced the output that it did.  I've only been programming in this language since I was in high school, and in this particular dialect of it for well over half my life.  And my boss knows it.
