Worked security at a hospital, and was responsible for signing corpses over to the funeral homes. One week, there was a car wreck in a nearby small town- a pickup truck flipped and rolled with five or six teenagers in the back. I spent the whole night rolling them out of the freezer and passing them off to various funeral homes.
I’ll tell you the strategy that worked for me last time (quit for ~2 years), and that I’m using this time.
Good luck.
