I actually had a guy leave payment and the key to his house under his doormat once while he was on vacation so I could deliver an arcade game.
Damndest thing. The envelope said something on it like, "Steve, make sure you leave $200 in here for James."
I took my money, went inside his house, opened his garage, unloaded the game in there, locked up and left.
All I can say is that was an era when gas was cheap and nobody had Paypal. Never heard a word from that guy again. I'm still shocked someone would be that trusting and still shocked I drove 125 miles each way to deliver a game without payment up front.
