It is not respectful at all.
It is a joke.
Well then, they should shove the second best player in the world off to court one, where there is no TV coverage, and not enough room to get the people in who would want to see it, whilst Cilic and Hewitt play in an almost empty centre court? If the crowd expect to see Andy on Centre and then he is moved to court one the crowd on centre will move to court one if they can, to see Andy. Any who can't will probably just go.
I think that crowd on centre would expect to see Andy on it. It would make no sense to move him. I doubt very much that Cilic and Hewitt will care less where they play, as long as they can get done today.
If it was a slam you might have a point, because there would be more than one big court. At a tournament like this Andy should be on centre. Nothing disrespectful about it.
