Suppose I have gone to the movies(cinema). There is a man behind me that cracks sun-flower seeds open, talks with the next person, and also talks on his cell phone. I want to say that these behaviors are annoying when I am watching a film in the theater. If I say, "When I am in the theater, it really bugs me if somebody behind me starts cracking seeds, talking with somebody, or answering his phone,” does this convey what I mean to say?
Is "to bug" a proper usage here?
Is to crack seeds open a proper usage here?
