This reminds me of the book Telephone by Percival Everett. No secret extra ending but there were multiple versions of the book, one with a dramatically different ending. I really enjoyed reading it- and then looking up the differences.

Yep and I hate it

I always flip the 30 buttons and then accidentally click Accept All because it’s in the place that I would expect the Confirm My Choices button to be and I am tired of looking at all the buttons and don’t read the most important one. I always tell myself I’ll slow down next time, but I’m just trying to get to the stupid website to read whatever stupid link I clicked on so I’m impatient every time.
