When I was working for Thales, I spent some time at their sites in France. No open plan. Big offices with between one and three people in. Often with glass dividers between offices (or rather, proper wood walls up to about waist height, and then proper glass to the ceiling). Big, chunky desks. Wooden things. Proper wood, rather than IKEA style. I've not explained that well, but you might know what I mean anyway.
It was so quiet. So much space. So good. Then I came back to open plan in the UK

Oh, oh, and the lunches. The food was so cheap, but so good. I hesitate to call it a staff canteen. Staff restaurant. With table wine. When I mentioned open plan, they gave a Gallic shrug and a "it's not for us" grin.
I'll shut up now. This isn't the Moschops Memory hour.
