IT WAS A NIGHTMARE for all Lane Crawford shop assistants, but thankfully for One Night Only, the party's theme for the evening. Lane Crawford threw open the doors of its newly revamped Central flagship store, and let shoppers swill its champagne and nibble on hors d'oeuvres while they pawed at expensive merchandise. The event also turned out to be somewhat of a family affair, as parents such as model Janet Ma and her actor-husband Michael Wong, entertainer KK Cheung and actor/businessman Michael Miu Kiu-wai and his wife Jamie Chik Mei-tsang brought their young children along, but maybe not just for the shopping. Perhaps some of the youngsters were lending their moral support to the 30-strong choir of the Beacon Hill School, who belted out Christmas carols. The store's ladies' shoe department on the ground floor looked as if it had been hit by a tornado. Frenzied shoppers tore through the goods in their attempts to use the coupons received with their invitations. For every purchase of more than $5,000, $2,000 was discounted as Lane Crawford's gift to their special customers.
