“The service of internet booking is not only outside the realm of Entertainment Tax Act but is an independent and an optional service provided by the cinema owner. It is neither mandatory nor uniformly applicable to all. If one opts for the online booking, one will have to pay something extra. But that has nothing to do with the gaining of the entry into the cinema hall for which one separately pays Rs 190.78 paid by all others who buy their tickets at the counter of the cinema hall,” the bench said.
