>>> say “hello” first when talking to someone, the absence of a hierarchical relationship between hospitality personnel and customers

These two are generally adhered to in the US as well. May be the hierarchy part is there if you're staying at really exclusive resorts. But by and large, most folks are polite.

There is obviously the random asshole. But those exist everywhere.

I'm not sure; granted I did not visit a lot of places in the US, but when I was there (Miami/Denver/Phoenix), I virtually never saw e.g. a customer greets the cashier when buying things.
