When families gather for Christmas dinner, some will stick to formal traditions, that is, their tables will be set with the good dishes and silver bowls. But now in many other homes, this china-and-silver elegance (优雅)has given way to a stoneware (粗陶) and informality, with dresses in an informal and ordinary look. For hosts and guests, the change means greater simplicity and comfort. For makers of fine china in Britain, it means economic hard times.
Last week Royal Doulton, the largest employer in Stoke-on-Trent, announced that it is removing 1,000 jobs -- one-fifth of its total workforce. That brings to more than 4, 000 the number of positions lost in 18 months in the pottery (陶瓷) field. Wedgwood and other pottery factories made cuts earlier.
Although a strong pound and weak markets in Asia play a role in the downsizing, the layoffs(失业) in Stoke have their roots in great social changes. A spokesman for Royal Doulton admitted that the company "has been somewhat slow in catching up with the trend(潮流)" toward informal dining. Families eat together less often, he explained, and more people eat alone, either because they are single or because they want to eat in front of television. Even dinner parties, if they happen at all, have gone informal. In a time of long work hours and busy family schedules, busy hosts insist, rightly, that it's better to share a takeout pizza on paper plates in the family room than to wait for the perfect moment or a "real" dinner party. Too often, the perfect moment never comes. Iron a fine-patterned tablecloth? Forget it. Clean the silver bowls ? Who has time?
Yet the loss of formality has its down side. The fine points of etiquette (礼节) that children might once have learned before at the table by observation or instruction from parents and grandparents (" Chew with your mouth closed." "Keep your elbows off the table. ") must be picked up else-where. Some companies now offer etiquette courses for employees who may be able professionally but inexperienced socially.
