I seem to vaguely recall that in one of Heinlein's science fiction novels the society considered eating to be a somewhat shameful process to be done only in privacy whereas shitting (and by implication, farting) were considered just normal public, even social, activities.
You might do well there, @trumpman!
Hmmm, never read any of his novels but after reading about him I think I will like them. I tried to google the "plot" you mentioned but came up with nothing. Oh well, I guess I have to take them from start!
