Movie night

I'm at the movies with my 5 yr old nephew. A woman with her kids just yelled at the 16 year old kid running the snack counter because she blatantly brought in outside coffee and he told her she can't have it. She yelled "well I'm NOT dumping it out so you'll just have to live with it." There's signs everywhere that say no outside food and drinks. I dont want to live in this world anymore.
