Am I the only one who's confused - and thanking my lucky stars I was born in a peaceful era in which resources are plentiful? As the caption accompanying this photo explains:
"When the weight of a rationed product does not come out to even pounds, the point fraction table at the bottom of the official consumer table show point values for ounces. If the odd weight comes out to a fraction of a point, a retailer can collect an extra point if it is a half point or more. But if it is less, the customer does not need to give up an additional point."
