Okay, this is weird. Last week I sent some processed film off to have enlargements made, using the same type of film mailer I've used hundreds (no exaggeration) of time before. Yesterday, it was back in my mailbox, somewhat worse for the wear, with a code strip on the back and a cancellation stamp on the front.

Only think I can figure is that some POed droid mistook the return address on the back for the destination address. And didn't twig when they had to turn the mailer over to stamp the front.

Well, I have some unprocessed rolls to send off anyway, so I'll just open that mailer and add the contents to a new one.

Weird...
