Good one! Long queues was a striking characteristic of Soviet Union. There was a time in Soviet Union when the government was running low on basic food supply and wanted to eliminate lines so they instituted quotas on sugar, flower, etc. A family would go to a governmental agency and receive a document stating that this family is allowed to purchase 1 pound of sugar a month. The lines were partially eliminated with hungry people staying at home rather than in a line for a chance to purchase food products.
What a dreadful failure communism was. I'm so thankful that I was born and raised in the USA.
