The croissants a pastry whose very name means “crescent,” nowno longer resembled their eponymous shape.
Instead, they were more or less straight.
Why would they have done such a thing?

Uh-huh, okay, Harry.
Interestingly enough,The New Yorkerrevealed that croissants in France aren’t always crescent-shaped.
In fact, top-of-the-line ones made with butter are straight, while inferior margarine or oil-based ones are curved.

That would have made a great reason for Costco to claim was behind their change.
