There is a story about Evelyn Waugh (Brideshead Revisited, Vile Bodies &c) coming downstairs and finding the kids fruit ration in WW2, and eating his Son's (Auberon Waugh, of Private Eye fame) banana with gusto. The first one he'd seen in years.

I suspect fruit rations in the Mars city of Elon's vision will be sold to the highest bidder. Weight for weight shipping cost is one thing, growing is another, even with virtually "free" heat on tap.
