perhaps should have held out for refund of the entire core deposit.

I always insist on reutrn of unservicable cores. Partly because between
Margy's classroom and some other people, we have no problem getting rid of
aviation "junk" but further to help head off this sort of nonsense. If the
core disappears darned if I'm going to eat the core charge. If they don't
pay me for it, it's mine.

We have a particularly disreputable instrument shop in this area that tends
to gratuitously misplace unservicable cores. Of course, this is only the
tip of the disaster that they are.
