I don’t quite understand what it means here:
Abas knew how to cook only native food, and Cooper, a coarse feeder, found his gorge rise against the everlasting rice.
What do coarse feeders eat – fat meat, kipper…?
'Coarse' means, among other things, lacking in delicacy or refinement.
You can describe someone as being 'coarse' or having 'coarse manners.'
It would seem to me that a 'coarse feeder' is someone who has no appreciation of food unless it comes in a bun from a fast food restaraunt.
