Making you think

The price of a cup of tea. The BBC's From Our Own Correspondent sums it up:

As I sat in the coffee shop in the airport fiddling with my bill, I reflected on the extraordinary state of affairs in Zimbabwe.
I had just bought two cups of tea and two glasses of water and, reaching into my bag, I took out a massive wad of Zimbabwean dollars.
New and crispy Z$10m notes. Clean and sleek.
Then I looked at the bill. The charge was Z$204m. That would make a serious dent in my brick of notes.
The Zimbabwean dollar is one of the most worthless currencies in the world so any notions of being a millionaire, or even a billionaire, lasted all of a few seconds.
