That's the economy right? We can take it a step further. If you are getting a burger from McDonalds, and you are using their self-service kiosk, there is a whole world/economy behind that. Software, Hardware, Touch Screens, CPUs, Connection, etc... If you are using an international card to process your order, there is a whole set of banks (throughout the world) involved in that particular and single transaction.

This kind of makes you think: All that efficiency comes at a cost (fragility). There should be contingencies to that. (ie: Cash acceptance is mandatory, at least one human kiosk, a list of close food suppliers that you can use in case your supply chain breaks, etc...)
