There's a common misconception in the world that anything which doesn't require a fiat currency as payment for goods is somehow considered to be "free". However, there are many other ways in which a business can "charge" for something. The beauty of this correlation exists when a business is able to capitalize on this feeling or sentiment that they are getting something for free when in reality they are simply paying a price in a different "currency".
I'm reminded of this in particular today due to the unique and highly successful free marketing campaign held by the restaurant, Chick-Fil-A. If you live in an area where this chain operates then you probably are very aware what today is. For the rest of us, today is colloquially known as Cow Appreciation Day. 🐄 In other words, should you choose to assemble a few bovine accoutrement (dress like a cow) and plod into one of their establishments you will be herded towards rewarded with a free meal.
The allure of free at the low, low cost of your personal dignity and a few cow spots dotting your personage. 😉 Bravo to Chick-Fil-A for a brilliant and highly successful marketing campaign. They have identified a marketing campaign which maximizes their brand visibility while also meeting the free mentality of their customers.
