The story as I heard it:

Before the start of the show, Mahesh had been on stage talking to Asela (actor from Sydney) who was in full make-up and costume. It was impossible to recognise Asela because of the long beard. Then some Canberra guy had brought a cup of tea and given it to Asela. Asela had held it in his hand without drinking, waiting for the guy to bring a tea for Mahesh as well. In a moment, the Canberra guy had returned. He hadn't brought a tea for Mahesh. Not only that; he had also grabbed the cup of tea back from Asela saying, "I thought you were Diddeniya." (Diddeniya was the main actor from Sri Lanka who played the role of the King.)
