Buckeye seems to feel his rights as a ticket holder were being marginalized.
Most theaters are THX-Certified, and it sounds like they weren't running it as such. (with the volume not at realistic THX levels)
I think Buckeye was entitled to a free ticket, or two, or his money back, to keep him happy. As the soccer moms were kept happy, with the volume being turned down.
The point I was getting at, when I mentioning a 'franchise', is that type of owner and/or business isn't really private, and the franchise has a protocol in place to satisfy customers, and it's operation.
Also the 'franchisee', is beholding to the 'franchise', and has lost some of his rights, in the franchise process. The rights, a private owner would have.
It's not the same as a mom & pop 'private' business. They can run it as they see fit, and the free market will decide.
I'm one that doesn't like to impose on other people.
If I'd felt the volume was too loud for my kid, or myself.
I would do, as I have done at concerts. I'd wear cotton or earplugs in my ears.
My wife and I gave up on getting ripped off with high ticket prices, and five dollar stale popcorn, years ago.
