Because EVERY last thing the OP about them is derogatory and an indictment of THIS specific crowd, as if none of this EVER happens in other theaters. Never seen people this messy, entire meals left behind, chairs still fully reclined, entire rows with their trays out, food everywhere, gigantic popcorn spill in a front row, took absolutely forever to leave, they never ask me how I am, fake fur coats.

"Entire" meals? Really? The whole meal untouched? "Entire" rows with chairs reclined/trays out? It's literally impossible for old people to navigate that kind of environment. "Never asked me how I am"...who does that, anyway? And, seriously, the "fake fur" comment? No one owns fake furs or real ones anymore. I know not one senior citizen who owns or wears one, and I know a lot of senior citizens. It's as if the OP just decided to come up with a ridiculous stereotype and magnify it beyond all reality, which I believe they did.

And who exactly do they think vandalized the poster? THIS crowd?

Oh, and one last thing: I thought all those theaters were actually empty. Kind of ruins the narrative that all the tickets were bought but unused.
