What if the concern wasn’t that he would have to use a disgusting bathroom, but rather that he takes horrible shits and didn’t want someone to know?
I mean, I’d certainly be embarrassed to have to tell the internet something like “I’m visiting my in-laws for a few days, and I really want them to like me. The problem is that I shit like a farm animal, and they only have one bathroom.”
Training isn’t a bad option, though, especially since some jobs will pay you for it. Some trades do paid apprenticeships - the pay isn’t great, but it’s better than paying for training.
Alternately, manufacturing jobs can be pretty good. I had a friend who got a job working in a factory right out of high school - he started at $20/hour, with a sizeable raise after the first year.
