They were working in a cockpit factory. They had many other options for charging their phone in a USB socket, and they still chose to charge it by plugging it into the cockpit. Your solution, in this situation, already existed and people still plugged phones into the cockpit.<p>Why would they NOT do this, under your system? If I can plug my phone in right where I am, in the cockpit, or somewhere <i>less</i> convenient for me, why would I <i>not</i> just do it where I am, in the cockpit? There are no penalties for it, so why wouldn&#x27;t I do it?
