I think I know which goof this is... he needs to be put out of our misery.
I was on int'l first (paid, not miles, not that it should matter) on my return home when connecting to my domestic flight, and i encountered him.
I showed my boarding pass, and he said, "Oh, you figured out the super
secret way to get in. This is a private club. United should really enforce members-only blah blah blah..."
