Well, when I first got into the business, I was a high school dropout (8th grade) with no special training or qualifications whatsoever. I figured that I could NEVER get into a career as prestigious as outhouse cleaning without a college degree or even a high school diploma.
Just for the hell of it, I applied at the local shithouse where they informed me that their regular guy was in the hospital suffering from colon cancer, so they had an opening. I took it.
The next few months were spent learning the trade from a guy named Sal. He showed me the intricacies of scrubbing fecal matter off of toilet seats, and within a few months, I was a certified Crappercleaner.
I'm trying to distance myself from it, however. The industry has become more obsessed with the money than the pure joy of cleaning up other people's waste matter.
