I got the email from paypal with the refund before the email from the processor, so I was puzzled for a while. If it was anything important I'd be mightily cheesed off, but as it happens it was no big deal, as it was largely an exercise in getting used to the camera again, and seeing whether I should use or dispose of the outdated film. I'm pretty sure some of the exposures were by mistake (not locking the shutter release after winding on then accidentally pressing one of the two shutter release buttons) and possibly one or two (non-) exposures with the lens cap on. So those mistakes were possibly not as expensive as I'd thought.
