Milk is often in the very back corner of the grocery store, as far as humanly possible from the entrance. It’s a strange location for milk, because it’s one the most popular items. A common explanation for this location is that by forcing customers to walk through the whole store, they will pass more products and end up purchasing more. But is that really why the milk is in the back? Can you really have a business model intentionally built around inconveniencing your customers? Today on the show, two big theories to answer this little question: Why is the milk in the back of the store? The theories reflect very different world views. To try to discover which is right, we host a friendly debate between food writer Michael Pollan and economist Russ Roberts.
