And judging from your absence, perhaps you have passed on as well..?
I once shared your morbid curiosity, applied appropriate initiative, achieved an entry-level position & moved^up from front desk clerk/receptionist [fancy bs title to impress] to an apprentice embalmer, acquired the necessary prerequisites for school [time & 200+ embalmed peepages] all-the-while taking mental notes and observing the licensed staff on salery and their job satisfaction/personal lifestyle/duration between pay increments & amount of bank, etc...
Eventually I concluded the overall package was not as previously perceived and bailed before enrolling in one of only 2 available schools in the state at the time.
My experience was unique to the industry because my employer was the industry [meaning not a mom & pop business] but the largest funerary conglomerate on the planet and what could be called the Wal-Mart of the funeral business aka Service Corporation International, SCI as it's known. Not the standard to measure by comparison, just your typical emotionless machine of consolidated locally acquired mom & pops into 1 primary-prep-room facility aka a 24/7 body factory that serviced outlying satellite locations providing pick^up, processing and redelivery of perfectly prepared & boxed dead peeps to the scattered store-front locations that rarely had functional on-site prep-room accommodations of their own.
I found the whole deceptive process disenchanting, but hey I punched that ticket & gained inside knowledge, parting w/o regret nor looking in my rear-view-mirror.
Bottom line, if your curiosity is genuine vs the typical pitfall of wannabe notoriety, my advice avoid Robert Waltrip's Wal-Mort and go mom & pop.
Now rest in peace y'all creepy mother fuckers lol.
