What got me is just the way it is phrased. They specifically didn’t say they were using such, just that it’s a thing. Like someone who has to go look up an answer. And yet, if someone called them out on it (like you did), they can turn around and say they didn’t say they used it.
I’m a native of L.A., and I’ve never once heard the phrase “L.A. culvert.” Yeah, it kinda looks like that, but parts have been encased in concrete for ages because of horrific flooding in the past. If it saves lives, I don’t care what you call it.
I have a mentally ill nephew who sounds exactly like this guy. Exact same disordered thinking: “if only I do this one [completely unrealistic] thing, I’ll be able to accomplish all the things that’ll turn my life around” despite years of experience which say otherwise, would be homeless if not for parents who can afford a place for him to live, etc. I have no idea if this guy is trolling (most likely is), but he sure has the plot down.
An actual homeless person would know that most (if not all) hotels require you to sign in and out, both to ensure that their own customers are the only ones using them, and to make sure that anything you do on that computer is secure from the prying eyes of the next person to use it.
