A pair of my friends woke up to a confused complete stranger on their couch today, and after some investigation the situation seems to be that he got shitface drunk at a strip club, drove to a Plaid Pantry (local convenience chain), bought some things, walked off with his car still running in the parking lot, wandered into a neighboring building, climbed three flights of stairs, opened an unlocked door, passed out, and woke up with the sense someone had driven him there to sleep it off but unsure why his car keys were missing
