I am interrupted, and when I am is generally somebody giving me a useful quick update or an informal greeting from an office buddy when they notice I make welcoming eye contact.
I don't think I ever felt a lack of privacy in the office or expected it in any way? I wonder what kind of privacy I would need that the restroom doesn't cover, I'm sure there are some instances since it's been called out.
It suits people that coffee badge and serves as a way to scan who actually came in on a "required" office day.
Both are signs of dysfunction.
Sounds like, oddly enough, eighteenth century London when coffee houses provided venues for business transactions. People (ok men of the right class) toddled around visiting various offices and patronising coffee houses. Everyone knew the players. [2][3]
I think this might be a good development. Meet to drink beverage and achieve 'common understanding' in the sense of the Royal Navy. Then disperse to various private locations to actually carry out the tasks. Would suit a '15 minute' city layout very well.
