At a job many, many years ago I asked a developer on a different team (across town) to email me an XML file I needed for a feature I was working on. After a few hours of not getting anything I checked with him and he said the file was too large and the email server wasn't allowing him to send it to me. It was a few hundred kilobytes, it shouldn't have been a problem but I didn't care too much, I just wanted the file so I asked him to zip it up to reduce the size. A few minutes later he said the email server was still rejecting it, even as a zip file. Getting frustrated, I grabbed my laptop and drove to the other office. He showed me the XML file... which was a Word document with screenshots of the XML document opened in an editor.

Exasperated, I asked him why he couldn't just send me the raw XML file instead of putting screenshots in a Word document. Turns out the document was on another system he had to remote into (with Citrix, I think? I don't remember what was used back then) and he wasn't "allowed" to copy files off that machine.
