Ah ha! I had always wondered why we'd buy a crate of 24 eggs at Carrefour in France when I lived there for two years, just off the grocery floor. I didn't feel bad not refrigerating them there, but of course must do so again now. Satisfying answer.
I live in Italy and most supermarkets only have refrigerated eggs with Carrefour being the notable exception and I found it weird when I first saw eggs outside the refrigerator
