How is it that a Navy supply ship was out of Coca Cola... for months?
Mr. Roberts commented early in the movie that he hadn't seen a Coke in four or five months. I would have thought that a Navy supply ship would have had ample supplies of Coke - maybe even provided to the Navy free (or at least low cost) by the Coca Cola company in an effort to contribute to the war effort. I know the movie was embellished for both humor as well as drama, but that line about not having seen a Coke for 4 or 5 months really didn't ring true.
But then again, maybe their supply chain was "situation normal, all fouled up", so something like this actually happened, even on supply ships which would be the logical place to find stocks of Coca Cola?
