This is what happens when your currency collapses

Icelandic banks collapsed last year, causing a run on deposits and their currency, the Krona. The economy imploded, drowning in debt and over-speculation (sound familiar?) amidst a financial crisis. Inflation soared overnight. As a result, the McDonald's hamburger chain is closing all their franchise restaurants in Iceland.
