Books I will never write (but should) Part One

In my travels I find the grocery stores/markets to be an underestimated proxy for culture. The book I will never write (but should) is "What your country's grocery store reveals about its people":
An entire aisle for soda in the USA!?
An open air market with laundry baskets full of mangoes in Taiwan?
As much room for cheese as for meats in the deli in France?
You get the idea I think...
