You realize that in real-life, this is basically like someone coming up to you and saying: “Jimmy told me to tell you to give the money to Johnny Two-toes“, but you have no idea who this guy is, so you hold out your hand and test him to see if he knows the secret handshake. If he does, then he must be part of your gang and you do what he says… if he doesn’t know the secret handshake, you decide to shoot him in the face (you have anger issues).
