How did rationing work in WW2? How was it received in the various countries that implemented it?

Hi to Indy and gang! I’ve enjoyed the several series you’ve produced and look forward to seeing more in the future. I’ve been going through some of my grandfather’s papers recently and I found USA ration book from WW2. Seeing this got me wondering: How did rationing in the USA and elsewhere work? How was it received in general? When did it begin and end? I can’t think of a better group of people to answer these questions than my fellow soldiers of the Time Ghost Army. Thanks in advance for your insights into this matter. Keep up the good work! Don
