The problem is definitely with the people using their phones, oblivious to the world around them. However, PT, while YOU might be working your tuchas off at your job (and thank you) but not all of your colleagues do. (I don't know which theater you work at, obv.) I can't/won't complain until intermission -- but that doesn't do me much good, for Act I, does it?
I agree: if a text message is impossible to miss, then you shouldn't be at the theater. People don't care about anyone but themselves - which is the long and the short of it.
If we're not having fun, then why are we doing it?
