Maybe Catherine would care about this blatant violation of movie theatre etiquette if she were better socialized, but as it is, Catherine rarely notices anyone else's behavior enough to make an evaluation on it at all. She's far too focused on other things.

"Oh, really? Ugh." She wrinkles her nose in an expression of distaste. "I didn't know I was signing up for hours of wasted time and bad acting. I just wanted to see what old movies were like."

She is not the brute-forcing type. She might be an android now, but she is not a particularly strong android, and Catherine has never actually been as bossy as she might seem. She doesn't like conflict, with people or with inanimate objects or the environment, and she'd rather passively wait for the movie to play out before leaving than struggle against it.

Not that she'll wait without complaining.
