Phonetic transliteration of 'Kinkos', the U.S. copy/print chain founded in 1970. It was renamed FedEx Office (联邦快递办公) after the 2004 acquisition, so the name now mostly survives in subtitles and older dialogue.
usage
Each character is purely phonetic: 金 (jīn) for 'kin', 科 (kē) for 'ko', 瑟斯 (sèsī) for 'kos'. Don't read meaning into them.
