Maybe this is a good start to promote bitcoin at all, because how? if not his kind of ways? But to think the fee to spend for small amount uhmmm  unless Coca Cola Company offer minimum order to use bitcoin, because surely if payee just put small amount to its transaction fee then I guess it will took days for Coca Cola receive the payment. But I believe that this company knows the good reputation and how bitcoin works that is why they engage to this kind of strategy.

Cheers for Coca Cola, hope to here more about the progression of this, of how many people avail drink using bitcoin thru vending machines.
