If it's anything like my grandma told me about what her mom said about how it was back in germany, people will just buy everything they need for a month the moment they get their paycheck. All money that is left over is then used to fire the oven or cover the walls where repairs are needed or even fed to the livestock. The money was essentially worthless within a week, after that it was less useful than the materials it was made of so people used it for that.

(Oh and another fun one was always when my grandma tells of the month where the money wans't enough for a month they had to live of their own potatoes exclusively for 2 weeks cutting into their income)
