Had that happen to me once. Figured the guy was casing as well. So when he asked for “Jasmine” or whoever, I changed the name up on on him. I said “Are you sure you have the right address? Where does Yolanda live, maybe I can point you to the right house. Or just tell me the address you are looking for.” He basicly said no thanks and turned to leave. I told him that I would be happy to go down to my friends house who was a deputy - I’m sure that he would know where their address was located or at the very least I could go down to the neighborhood watch block captain and he would know.
Of course the guy passed and got into his car and left the neigborhood rather quickly.
I like that, the deputy..lol
Clever! But not as clever (and audacious) as what someone I know did. He opened his front door wide and, grinning a mile wide, replied "Sure, Carlos [in this case, the fictitious name was "Carlos"] is inside waiting for you! Needs help carrying something out to the car, so lend a hand!" The would-be perp was, of course, taken totally off-guard and immediately started backing up. It was then that my friend produced the shotgun he'd been holding the whole time behind the door.
