@ehBeth,
Well if it the distraction is bad enough, I've done that, too. But luckily that hasn't been necessary, too often
Some years ago I attended Saturday afternoon session of a film by an Iranian director (whose films were banned in Iran).
The theatre was choc-a-block full of recent Iranian migrants, with their whole families. Mothers, fathers, children of all ages, grandparents ... they were beside themselves with excitement at certain points in the film, like when they recognized certain locations, or at developments in the plot, etc.
And were unable to restrain themselves from exclaiming, discussing the action loudly, etc, etc.
It was a cacophony!
We did our best, but it really was impossible to follow the plot, concentrate on reading the sub-titles & not be completely side-tracked by the goings on of the audience.
So after about half an hour of this, we left.
The theatre manager was completely sympathetic, gave us substitute tickets for any future session of the film.
But I saw his point. This was a really important event for the Iranian audience.
And what was he going to do, throw out just about everyone in the theatre?
