After being in IT for a decade it never ceases to amaze me how incompetent people are when it comes to tech.
At my first gig in NYC I worked at a smaller financial firm (about 100 people) and every mid-level and above employee was given a work phone. One time I got a ticket that said "my smartphone is being really slow, can someone please take a look?". I went up there and it was a guy in his 40s (I was like 30), suit and tie, I think he was a Junior VP or something like that. He gave me his Galaxy S5 and I looked at the RAM usage and it was all taken up by Chrome. I opened up Chrome and he had 99+ tabs open, I told him that was the reason and he said "Oh.. I thought those automatically closed when I exited (he meant switched apps, not killing the process)...", I told him they didn't and started swiping them away, after the first few it was about 90 tabs of (teen) porn 🤣. I had to stand there in front of him, straight faced for a good few minutes cleaning up his porn. Afterwards I said "it should be better now, just remember to close your tabs when you're finished with them." and left. Once I got in the elevator I nearly pissed myself laughing so hard.
