theshhh - What we all need to remember is that every single piece of information about the Royal Family, every SINGLE piece, comes from the media, whose job it is to sell papers.
If you look at it from that point of view, which makes more sense in terms of exciting the public and selling papers - the princess popped along to support her good friend playing a tennis match, and said nothing to anyone about anything to anyone, or a royal aide 'demanded that no-one took her picture', making her look like a pompous diva, in keeping with the media need to churn out endless 'reports' to make her look controlling and generally unpleasant.
We have the word of someone who sat near her, and instantly felt the need to tell the Telegraph, who equally instantly felt the need to tell everyone else, so we could all be outraged by this awful behaviour.
From your post, this has clearly succeeded, you are outraged by something unproven, from an anonymous source, which clearly chimes with your dislike of the Duchess.
But the actual fact is, you know nothing whatsoever about any of the Royals, except what the media tells you, and they have an agenda to promote, and this is them doing it.
The Duchess may be an utter pain to be with, but I would never believe it simply because an unidentified 'media consultant' (who instantly consulted the media!!!) said something negative about her, and probably got a fee for doing so.
