I always felt that they might have scanned every incoming application first thing as it comes through the door. Part of the reason for charging so much. Maybe they dont but it would be a way of ensuring that material doesnt get lost or even mislaid within their own building or if it does get lost then there are copies to refer to. And what about the duplicate set? What do they do with that? I always thought the duplicate set was a backup against losing application papers.....

So if they had your photos in duplicate, if they lost one set of photos then they would have had the copies to refer to. But like you say, they returned the photos to you. How bizarre.....

Our application included an index / list of contents.

I still think admin error / negligence and are maybe trying to hide it.
