I recently flew to the United States, and was watching the movie
Edge of Tomorrow (with Tom Cruise) on the entertainment system.

To stop watching and go back to the list of movies, there was a "Back" button in the top left. When I pressed it, the system wanted to make sure I really wanted to stop watching, whether I really wanted to go "Back".

And since I really did want to go "Back", I pressed "Back".
I was wrong (again).
"Back" was like a "Cancel" button, undoing your previous requested action, and I literally was caught in a loop for a couple of minutes where I clicked "Back" 10 times before I figured out what was going on and how to get back to the list of movies. (Yes, I had plenty of time to figure it out and nowhere else to go.)
Have you had similar UX nightmares?
For those who don't know, the title is a reference to the great series Twilight Zone, and specifically to the episode
Nightmare at 20,000 Feet (the 2019 remake changed the altitude to 30,000), which starred a young William Shatner.
The plot: "
A man, newly recovered from a nervous breakdown, becomes convinced that a monster only he sees is damaging the plane he's flying in. Everyone thinks he's crazy."
