Common courtesy? Same with being nice and polite, saying hello/goodbye, etc. It wastes time because you could get to the point faster but it’s nicer and makes the interaction more pleasant. That’s it. No other reason. Just make the world a slightly better place with a tiny action.

I don't think saying hello opens yourself up to lawsuits in the same way.
