Unfortunately.
My stepdad even used to make us smuggle in cans of soda in my mom's Mary Poppins style purse. There is nothing more humiliating than pulling out cans of soda when everyone around you is drinking from cups bought at the theater. And the cans of soda don't even last through previews.
We never smuggled in candy-we don't eat that at the theater. Instead we smuggled in cheeze-its, goldfish, chips, carrot stick, etc. We usually got to buy popcorn, but of course stepdad had plastic bags to split that into too.
Now I get to see movies on my own with friends. LOL. Nothing gets smuggled in. Yes we pay the outrageous prices-because we want the big sized stuff. Besides-smuggling food in is humiliating. Or at least it is if you're a teenager.
