Not really, no, it's just one more thing to go wrong and for me to have to dig out of my pockets. I'm happy for things to move along more efficiently, airplane processes are slow and annoying enough as it is. I don't care if some other guy got on the wrong flight, intentionally or not. That's his business.
As funny as I find the anecdote, I would prefer any airline knowing who's on my plane. Wouldn't you?
