And the real issue keeps getting explained to you! NYC manages to
operate without gateline staff because, as in Paris, the exit gates
don't require a ticket.

On a related note, the RER in Paris DOES have ticketed exit gates, and I
have been "locked in" unable to exit with no staff around to help.

Amazingly, I did survive the ordeal though! :-)
