I believe you, but my hunch is you're an outlier. I've lived probably a dozen places in the US, not to mention the likely hundreds of places I've slept throughout my life. I don't recall every having to wait more than a minute for hot water. Ultimately this is just my anecdata. Maybe your story is more common than I realize.
