Capacity may indeed be a reason for requiring advance bookings.

But it doesn't explain the ridiculous security (scanning gates, had to take off my hat and belt, insulin pump was inspected), the prohibition of "professional" photography equipment, prohibition of own food and drinks (again, diabetes, I want to carry some lemonade and a bar for emergency), etc etc.

Is it to counter terrorism? To boost consuming at the establishments? Or is it a lame excuse thats in reality just a higher bar to entry?

Ok that one looks legit :)

I was thinking more about his experience with e.g. the last one on the page, Roof Garden at The Post Building:

> I still don't understand why it's here nor why it's open daily, nor why they insist on Photo ID "and a full written name" before they'll let you up. However I didn't get the chance to test this out yesterday because when I arrived the roof terrace was "closed due to essential maintenance work", inconveniencing probably nobody but myself.

Lived in london for over a decade, never been and I also don't think I know anyone else who's been.

To be fair it's not just that, you won't find many actual londoners in central full stop unless they're going to work

I mean they also seem to charge it? (According to the blogpost) then how is it free to the public?
