Miss Argentina (aka The Receptionist / Miss Receptionist) appears at the window in the Neitherworld waiting room. As shown in the film, she appears to have committed suicide by cutting her wrists. As she says to those Afterlife victims: "If I knew then, what I know now, I wouldn't have had my 'little accident'". That's what happens when those people (including Adam and Barbara) died, although her statement was likely not knowing until it was too late that Netherworld law stipulates that those who died by suicide are assigned to work as bureaucrats.
She seems to not care too much about the recently dead.
