Oh wow. Movie theaters can charge whatever they want. If the tickets and food are too expensive for you...you don't have to go there...you could wait for it to come out to some rental service, or go to OnDemand on Comcast. It will probably be posted there soon and you can rent it for a night and drink your own ice water for free. And if you can afford a boob job...you can afford $5 for popcorn. Do your research...stop complaining about life.
Oh, also the "combo deals" usually don't save you any money. They are the same price as buying the drink and popcorn or other food separately. People don't do the math and take the theater's word for it so no one notices it.
