You're the doorman/women for the apartments, the year is 1975 and your job is to keep doppelgangers out of the apartment

You met the milkman (Francis) a few times turning your shift and have became friends with him, he might be hard to read but he's a really good guy!

Anyways..Today was no different than any other days, checking ID's, calling the D.D.D if you found a doppelganger (and they'd be there in seconds), and overall it's been going good..till the milkman comes and slides his ID and Entry request into the little slot

"Mmh..hey" he says, looking at you with his normal-tired eyes
