Silicon.com: Colonal Sanders has tried self-service and, if customer response is any indicator, it's finger-lickin' good. A KFC franchise in North Wales began trialing self-service kiosks in Aug. 2008. Customers can evade long lines by ordering and paying for their meal at the kiosks. The user interface for the kiosks, provided by YESpay, has boosted the average order size from £5.83 (U.S. $8.01) to £7.93 (U.S. $10.90). Roughly 15 percent of the franchise's business takes place at the kiosks.
