I'll keep that in mind. Although being too nice I could always "accidently" spill the drink all over the phone and then pretend it was not on purpose .This person also spoke a couple of times throughout the film, although to her credit she at least spoke in a whispered voice. It seems not enough people actually respect the cinema with the same amount of gusto that I do these days.
I usually go out of my way in films to make sure I do not disturb the other viewers around me.
That's one of the main reasons why I never go to the theater anymore. Some people just don't have the basic civility required for living in society. So I recluse myself like a hermit in my cave
