I actually think cubicles’ faux privacy might encourage more noise. When I was in cubicles years ago, there were people who would take calls on speakerphone. I’ve never experienced that in an open office space, but it’s hard to know if that’s just because I’ve had more conscientious colleagues in open spaces.

I don't find open spaces noisier than cubicles but I am able to easily block out distracting sounds.

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.
