What tropes in books do you find the most egregious and why?

I recently started listening to a book I found under audibles free for members section called "Ruins of the Earth". I went in fairly blind except that it was sci-fi in nature. I won't get into spoilers for the plot, but I have decided not to continue because the book keeps doing something that entirely breaks my immersion.

It keeps having the first-person protagonist comparing the situations in the book to movies or other stories, and then clarifying that "this is real life though," which for me just completely reminds me I'm reading a book and takes me out of the story. I've only just gotten to Part 2 and I feel like they've done it four or five times so far.

This isn't the first book I've read where a character keeps comparing their situations to other works only to assert that the stakes here are higher, because this time it's for real. I hate hate hate it.

So I'm curious, are there any tropes that you simply cannot tolerate in books you're reading?
