Nowadays, people rarely use pay phones or mailboxes run by government. Instead, they prefer to use private services when communicating with others; they use mobile phones or gmails. As people find the contemporary public services slow and inconvenient, they avoid public communication points. Ironically, most of the public communication points such as pay phone booths and mail boxes are located at the high traffic areas. Put simply, relatively useless, public communication points stand at the highly useful, high traffic areas.
Therefore, many people propose to use public communication points for other purposes. For example, they suggest to use pay phone booths to charge batteries from mobile phones to electronic cars, to use the booths to collect traffic data, or to leave defibrillator, a device to give electric shock to someone’s hearts, for emergency.
