What is the central idea of this story?

the movie was about to start and i was ready. i had already sat through five movie previews, six trivia questions and at least twenty advertisements. it was time to begin this ninety–minute flick. i had already spent thirty minutes in the theater, and i was starting to get restless. i was anxious to see the movie. "let's get this show rolling," i said to my friend. "between the popcorn, the soda, the ice cream bar, and the tickets to get into this joint, i spent over $15. it is time for me to get what i paid for." finally! the screen presented the best two words i'd seen so far: "feature presentation" appeared in bold golden letters. i slouched down in my seat and started munching my popcorn in deep anticipation. suddenly, three cartoon bunnies bounced across the screen. by the time they met a cartoon farmer, i realized that we had entered the wrong theater. now i understood why there were so many little children in the theater. by the time we made it to the correct cinema, i realized i had missed over twenty minutes of my movie. i was furious. the movie had no meaning now. i decided to go back to the cartoon movie. at least i'd be able to see the whole thing.
