I’ve been Dude in the past. Yesterday I was probably in danger of becoming Dude but for my general introversion and maturity. I walked around listening to James Brown instead. I think flexibility and a culture demonstrating proper time management and production would help. It’s important to socialize but without detracting from others. Yesterday, I just couldn’t sit or stay at my desk - I needed some air. In hindsight, I was pretty amped up from a meeting.

Absolutely. You could argue that a water cooler/coffee machine conversation is unlikely to be distracting as compared to interrupting people at their desk. If people are by the water cooler, kitchen, canteen, etc chances are they wanted to get away from their desks and would be open to engaging with others (even if bery briefly)
