I had a meeting at our main HQ type building today. I took my rucksack over, to hold my notebook, and 'stuff', and in case I had documents to collect. After pondering for a while I decided to leave my camera in my rucksack. "If I don't bring it, I'll miss a wonderful photo op."
Surprisingly, the Fish and Parcels line train came immediately, so I decided to hang around outside the building smoking. The building is entered by a turning door, although there is a standard one that can be opened if necessary. I saw some chap holding open the standard door, clearly waiting for someone. I saw a Guide Dog appear and walk out the door, followed closely by the Secretary of State (obviously, I can't tell you who, because I would then reveal which Department I work for and that would be very naughty).
I was in a perfect position to get a photo. But my camera was in my rucksack.
Sigh.
