Back when I lived in my university dorm I shared my room with internet admin. Usually I helped people with internet problems when he wasn't there and I've placed FAQ on the door how to fix common stuff with a little note, that I can help only with internet problems and only with those that aren't listed. It worked for most people, but one guy knocked and messaged me around 5 times a day to fix his system. So I've decided to finally do what he wants.
He: come on, I heard from XYZ that you are an admin in job and you fixed her computer.

Me: but I work only with servers
He: what's the difference? Just copy my photos to my external drive and install new system on my laptop, just like you do it in job.
Me: so this is that simple job?
He: yup, but I need a laptop tomorrow, because I have something to do at the evening.
Me: okay

I've used find to copy all the photos from his HDD and installed minimal Debian without xorg on the laptop. He hasn't come back after picking up his computer. And that's the way to get rid of leechers that whine for fixing everything because you are IT guy :D
