Why is popcorn so expensive at movies theater's

Your a captive audience. It's the same on ferries and at airports.

They're so in hock. Figure the overhead costs of a multiplex. Especially in a mall at premium per square foot leasing rates. Theaters often only filled to 10% capacity. The hollywood fees to be high up the list in theater distribution and for permission to show for protracted time periods. 🤔

Or maybe they're still recovering their losses from when theaters were big rooms stuffed to the gills before TV was invented, and they charged a nickle a seat and gave you a piece of depression glass pie plate or dinnerware back in he 1930s.

It was kinda long ago though. Those big people who told me I was their kid said I wasn't born until years later. When it only costed 50 cents to go, but I'm only going on what I was told. How much is it anyway? A hundred bucks? I haven't gone to one of those in a coons age.

I sure hope that is a typo and you actually meant popcorn.

Because people pay for it.

Few things in life you can sell at a few thousand per-cent mark up !!
Popcorn is one of them !!
Don't we all get wise to this though and take our own ??

because they really don't make that much money off the movie tickets themselves - so they have to make the money off the concessions

Because they gotta make moneys and they can pretty much only sell movie tickets and food.

But you have to buy it cause it's do good.

I think cause they kniw we will buy it

Because they can charge it

Supply and demand...mostly demand
