Reminds me of someone I did a webpage for a while back.
I did the website and they liked it. About a week later they said they found a typo. That's pretty reasonable.
I asked what the typo was and the customer told me he couldn't remember off the top of his head, but he'd email me. Also reasonable
Over the weekend I got several emails from an email address I didn't recognize with no subject, no body, no attachments, only a broken link.
Somehow I figured out the emails were coming from the client. H was printing out the webpage, using a pencil to mark the spelling mistake, scanning the picture, saving it as a PDF and sending me the PDF.
OK, that' a far more ridiculous procedure than just emailing me the one word that was spelled incorrectly, but fine.
Except he didn't email me the PDF, he emailed me the location of the PDF on his hard drive.
