I have definitely had hot towels and free alcohol on US domestic carriers. I'm not imagining it.
Complementary alcohol - as a standard offering - is not normally offered to basic economy passengers on domestic flights in the U.S., and hasn't been for at least a couple of decades.
That said, some airlines offer it as a promotion on some flights [1], which may be why you have experienced it. But it's not a norm that any coach passenger could expect on any domestic flight, the way it used to be in the earlier days of commercial air travel.
The video you shared of hot towels being handed out in economy on a domestic U.S. flight was a one-off promotional event. It's also not the norm.
Like I said, I get that the two of you were talking about different things and were sometimes confused about what the other was talking about. But you did inflame things by asserting/suggesting things that aren't really the case.

As for hot towels, you'll have to do a lot better than a Youtube video with quizzical comments because apparently none of those people have ever seen it either. In fact, if it were so common, why would someone bother to post a short Youtube video of this? Obviously, given the focus of the short video and its title, the fact that they're handing out these towels is new and novel. And as I've said, I've flown domestically countless times, since the 1980s, and I've never seen this, ever. They would almost certainly do it for flights to/from Asia because it's normal there, but Americans aren't used to hot towels. After all, they never serve them in restaurants either.
