According to a recent and unscientific national survey, smiling is something everyone should do at least 6 times a day. In an effort to increase the national average (the US ranks third among the world's superpowers in smiling), Xerox has instructed all personnel to be happy, effervescent, and most importantly, to smile. Xerox employees agree, and even feel strongly that they can not only meet but surpass the national average... except for Tubby Ackerman. But because Tubby does such a fine job of racing around parking lots with a large butterfly net retrieving floating IC chips, Xerox decided to give him a break. If you see Tubby in a parking lot he may have a sheepish grin. This is where the expression, "Service with a slightly sheepish grin" comes from.
