shorts story, sf, mid 1980s or earlier

[fred_mouse]

Looking for a SF short story I would have read in the mid to late 1980s, from a collection or anthology borrowed from an Australian library.

Character A has done something bad to character B (or their family). Character B is from a community (alien race? planet?) which is famed for getting revenge. They are both at a gathering; Character B offers Character A some kind of fruit, with an explanation of something about this has to do with resolving the conflict. A eats the fruit, it is then revealed that something else that was in it (possibly a grub?) will kill them.

Could this have been one of George R.R. Martin’s Tuf stories? (Tuf was a comic-book-level bioengineering supergenius who’d go around doling out ecovigilante justice.)

Plausible. I do own a copy of Tuf Voyaging, and haven't read it in a very long time. I will have to work out which book shelf it is on!
