At my office everyone does the hello ritual. It's so ingrained if there's more than about 10 mins between responses, people will start the hello ritual again.

I once asked someone I thought was becoming a friend if we could skip the hello ritual since we're good friends. They were extremely offended. I gave up and just perform the ritual.
