Granted, your tickets entitle you to a seat behind a large concrete pillar.
An Existentialist might or might not make a wish, for something or nothing, and they might also forget to mention it or perhaps not care whether they mentioned it. It's likely they would consider the chances of a wish being granted as problematical or of no consequence in the face of life's absurdity...
I wish I could understand Existentialism, or just speak French....
