but can he be blamed for this?
I would have expected him to behave like the professional he's supposed to be and carried on.
Ok, so whatever was said to him was extremely personal and totally unacceptable in the light of his cancer diagnosis, and there's no excuse for a fan to behave in this way, but to storm off and disappoint all the fans that did spend their hard earned cash on going to see him?
There are idiots in all walks of life and unfortunately there will always be hecklers at these type of events. Security would no doubt have removed him and that would have been the end of it.
But instead all those people, some of whom no doubt paid for flights, hotels, time off work etc etc, got to see a 25 minute performance.
Ok, so they have the chance to see him for free in Kraków, but not everyone who paid to see him in Warsaw will necessarily be able to attend.
Diva like behaviour in my book and he's had a habit of walking off stage many times before...........
