When I was in a crappy IT support assistant job (crappy because people there were mostly dumb and expected miracles from me), this guy almost in his 60s calls me for an urgent issue. I get to his station and he's like, I wrote 20 pages in Word and then accidentally selected all and deleted it and pressed CTRL+S coz of habit. How do I get my pages back? I was like, it's gone. Overwritten. And he looked like he didn't believe me and was probably thinking that I was crap at my job. Pretty sure he complained about me behind my back to HR. File versioning wasn't enabled in the domain policy and I wasn't the domain admin (he was in another country) so no easy solution to that guy's problem.
One guy I was able to help was because he saved the document somewhere and couldn't find it. I started a full drive search on all drives in his laptop based on what information he could give me and he finally found it. He was so grateful to me that I thought if he had a daughter, he would tell her, worship this man!
