Back when I was a boy and Ben Franklin was still president, prep-packaged coffee always came in 16-oz bags. During the the '70s and the Nixonomics stag-flation wage & price freeze period, coffee suddenly started appearing in 12-ounce bags. I was just out of the army in 1974 and remember being amazed at how packaging had changed to, in many cases, evade the price freeze instituted the same year I entered the army in 1971.
If I'm wrong on anything here please correct me and win a handful of fat cigars from Mister Moo. If you're wrong, you owe me same.
