Limited to certain types of movies

Preference to checking movie shcedule on showtime. Get to the cinema, they tell me the movie is only playing in VIP, when there was no indication of it online. Or wanting to watch a movie that came out in both 3D and 2D, I wanted to watch 2D and they tell me at the cinema only 3D is playing when they have times for both online. Seems like a money making scheme!
