Everybody has a habit. Some people are addicted to smoking and some to drinking. There are smoking etiquettes everywhere now.
The smokers generally go out to an open space to smoke. They don't light cigarettes in the office room in front of everyone.
But a Tollywod director has a peculiar habit. That is chewing a kind of pan. He is addicted to it and cannot think without that in his mouth.
But the peculiar smell proves to be allergic to the star hero with whom he is working at present. As a bonus, sometimes, the drops of saliva from the director's mouth do shower out when he speaks.
The top hero is irritated by all this. Right now the shooting is not happening any way. It is yet to be known if the hero conveys the director about his problem.
