This isn't really true, most people do want pleasant and welcoming interactions. That doesn't mean jumping through hoops, just little things like saying hi and smiling.

The opposite - silence and stares - is uncanny, and has gotten much more common in the past 10 years. Everyone notices, and it brings down the vibe.

That doesn't mean forcing your workers to do X Y Z. What it means, IMO, is hiring workers who are pleasant. That would require a pay raise though, because you can't be picky at 10 bucks an hour.
