I heard something about pacemakers occasionally being left in bodies by mistake, and becoming small bombs in the crematorium ovens. That's gotta be a trip, the first time you hear that shit.
And then you probably have to get the oven inspected, to make sure the incident didn't damage the gas lines. And that probably costs at LEAST a few thousand dollars. And probably tens of thousands, if something does need to be fixed. So, like, I'm pretty sure the boss is only going to let one of those slide, maximum, before you're out on your ass.
The body is often "prepared" for the funeral before it is cremated, so tape a couple hundred dollars to your chest with a note asking the preparer to leave your guts intact. Usually an underpaid apprentice does this, so there's a chance they'll go for it.
An old coworker of mine at some part-time gig went to school and studied "Mortuary Science". Absolutely fascinated me. He had a second job at a crematorium where he was an apprentice.
After him telling me that, I realized that I never thought about how someone got into that field. Never really considered someone going to school to do this as a career (which now I realize is obvious, but I never connected the dots).
Always assumed people working at a crematorium or a cemetery was a cliche old decrepit guy.
