i dont think it was a secret for anything
but i once went to a job interview at a phone support line for an ISP in my country
it turned out to be ... a sales department. basically that's what they called it. all support calls had to eventually lead into selling something.
that just seems so idiotic i couldn't deal with it
You would also need.. a childs room with furniture, baby pictures, baby clothes and so on.
This is a possble prank to pull off but you need to place clues that indicates you have a child.
