You mean those times the boss scolds you about because you're just chatting in the hallway instead of working at your desk as it should be. Oh, you're having a quick in person discussion with a colleague with the white board? Did you book that room a week in advance? No? Well, do that meeting somewhere next to people trying to focus. And why are you all standing around the desk for? Showing each other's work? It's gossiping more likely. Back to your own desk!
That was my experience for the last decades until work from home really happened. I had the impression many bosses liked to stop chance encounters so you just did your best keeping quiet and pretending to be busy. Encounters happened despite the environment, not because of it.
And then suddenly in the last year talks in the hallway were the most important stuff ever. Sure.
