Okay, I again pondered the Las Vegas Leviathan's plight, that of not having a job, during the night.
His feet hurt, so that eliminates any job that requires one to walk around.
However, one has to do at least a little bit of walking anyway, some minimal amount.
Apparently it was prevalent in France during the earlier part of the last century, to have an old woman with a chair and table (on which sat a bowl), inside public sanitary facilities used by members of the male race.
I'm not sure exactly what such women did--perhaps cleaned the room as needed, perhaps resupplied whatever needed resupplied, perhaps deterred unrespectable conduct--but they seem to have made a good living, from the centimes and francs male patrons tossed into the bowl upon leaving.
I've never been to Las Vegas, but I'm sure there's a lot of men's restrooms all over town.
The Las Vegas Leviathan could perhaps approach the owner of such a facility, offering to keep it clean and to discourage lewd activity, in exchange for the "right" to set up a chair, table, and bowl in it.
He could sit in the chair most of the time, getting up only rarely to tidy up the place and replenish the soap and bathroom tissue, and guarding against bad-mannered behavior. It'd probably be a 95% sitting-down, 5% walking around, sort of job.
And this being Las Vegas, no doubt grateful patrons of the plumbing would drop $10- and $20-bills into his bowl, rather than nickels or dimes.
