...that by offering you new titles so early they are going to lose on all the overpriced cold drinks, and snacks they sell you at the theatre.
This is incorrect. Movie theaters make ZERO money on ticket sales for the first few weeks, then a small portion of the ticket sale, and then eventually a good portion. Pretty much ALL ticket money goes to the makers of the movie.
THE REASON why you have those overpriced drinks and such, is because it's the only source of income for the movie theater itself.
