What do you think might happen if someone tried opening a Retrospec package that wasn't meant for them? Like if you get the job, and you see that your sister got one, so you try to see what's in it?

[ besides the fact that you're breaking a federal law but that's besides the point. ]

Although maybe there will be some magical bullshit that happens and mysteriously enough you never end up with Retrospec packages when it's your shift.
