I just wonder. Back in the old days what would we have thought of other players who would unfold a newspaper and read that while we're playing? I suppose that pretty much anybody would have found that to be very rude. It sort of shows that you don't take your opponent seriously in some way too.
Practising alone is a totally different story and I would never be offended by people wearing headphones doing that.
But another person demonstrating their lack of interest in your gameplay .... I don't take that well.
