This will be long and it's more of an IT rant, but I think it still fits.

So a user comes to me and says "hey on my phone I can't see anything in my junk email folder but there are a bunch of emails in there on my PC." I take a look at the Outlook app on his phone. The "Junk" folder that he has open is actually in his deleted items folder. So clearly it's not the real junk folder. There are no other folders named "Junk", but there is one named "Spam". I open that and there are a bunch of emails in there.

ME: "Does this look like what you were expecting to see?"
USER: "Oooohhh so you think it's called "Spam" instead of "Junk" on my phone?"
ME: "I'm not sure, does this look like what you were expecting to see?"
USER: "See, I always thought junk and spam were two different things."
ME: (grinding my teeth and taking a deep breath) "Does. This. Look. Like. What. You. Were. Expecting. To. See?"
USER: "Yeah, looks like it."

OK THEN FRICKING TAKE YOUR PHONE AND GET OUT OF MY OFFICE.

I didn't really say that last bit, but I sure was tempted to.
