This somehow seems to be beyond today's population and society. How dare this weather impact my schedule!
You can no longer shift your activities when the weather reaches 35C (95f) every day for weeks without noticeably cooling down in the night.
And even if activity shifting was possible, which again, it is not anymore, the authoritative, fatalistic poverty mindset required to demand that one does not actively cool during hot hours is a European mentality not many other cultures, if any, understand.
I do not 'demand' you do the same. I just point out that there were options besides cancelling the meeting, some involved airco, LSE has airconditioned meeting rooms, admittedly without the gorgeous historic atmosphere, some didn't.
I'd grant you that you didn't explicitly advocated for restrictive AC regulation, but I claim your dismissive attitude is implicitly part of the reason AC regulation remains restrictive.
I speculate the restriction on AC in that conference room is because it is a unique historic location they want to preserve, not some ideological anti-AC dogma.
