I was unemployed in my early 20s for over 2 months during the 2008-09 recession. My bank account was overdrawn and my credit cards were maxed out. 2 $20 McDonald's gift cards from the "random stuff" drawer was a God-Send. Double cheeseburgers were still 99 cents then, and had nearly 500 calories. I'd get 1 a day and supplement that with some flour-water mixture I pressed into a cookie sheet to make hardtack https://en.wikipedia.org/wiki/Hardtack.
