Many years ago, I arrived to my half-height cubicle at a Fortune 100 company to see that my desktop PC case was ajar. I set the CRT aside, opened it, and realized that the RAM had been removed. My neighbor explained what must have happened: another employee must have needed to double their RAM from 8 to 16 MB. Requisitioning an upgrade was a weeks-long bureaucratic process that required approval by one's manager and IT, perhaps prompting a review of per-team resource allocation. Repairing a broken PC was a trivial help desk ticket; my PC was restored in an hour or two.

Sounds like the neighbor could have just taken the RAM from their own computer out and claimed someone stole it and then called IT to provide them with replacement and then opened it back to and put theirs in. Seems pretty selfish to disrupt someone else's day for this instead of your own; they could have gotten back up and running before you did since they could have put in a help desk ticket before you even got in.

Was this explanation given with a wink and a nod, or did your neighbor always have 16MB of RAM?

Reminds me of the kids in my high school who stole individual 4MB 72-pin SIMMs out of a bunch of computer lab desktop PCs to upgrade their approximately equivalent generation motherboard/CPU home systems to whatever was their max capacity, in an era when a 16MB RAM desktop PC was a high performer. Shortly after all the PCs got locks on them.
