I once delivered to a guy living under his porch if that counts.
I drove up to the house. Its pitch black. No lights on. I look at the ticket and it says "use back door." I go up the steps and no lights on. Nothing. Then I hear a voice from below me say, "hey down here."
I look under the porch and theres a small door leading into what looked like a makeshift apartment. I had to actually crouch to get to it. Gave the guy the pizza and bounced the fuck out of there.
