They are just trying to make money. For some of them it's just a job. If you want someone to say something about it, start with yourself. It possible they got it like that and think thats the way it's suppose to be.
Little story: I took my sister and her family to see Narnia 3-D over the holidays. At the end of the movie when the credits started to roll up the screen the music stopped. (I like to watch the credits and listen to the last song, helps cap the movie for me) Upon leaving I "complained" about the silent credits. The lady asked me to wait a minute, and returned with 7 free passes to a future 3-D movie, telling me it was a timing issue, and thanked me for being the first person that day to tell her.
