Cingular Wireless now offers a date rescue service that will call your phone at a predetermined time and prompt you with dialogue that will help you get out of a date. There are 8 randomized scripts that users will hear, and then repeat to create a ruse, and fool the person they are out with.
According to my fiancé girls have been doing this for years. They go into the bathroom, call a friend and ask for a rescue call 15 minutes later. Technology has caught up. There is a sad truth behind this and that is no matter how efficient communication technology is, it does not preclude good communication. This is just another piece of technology that we can hide behind.
