Model Amanda Strang ignored the chilly winds blowing through the city last Friday to arrive at the opening ceremony of Starbucks' Christmas Red Cup campaign attired in a pink short-sleeved mini, while actor Louis Koo Tin-lok played it safe with a black down vest with long sleeves. But it was a warm event regardless - Judy Chen, chairman of Hong Kong Committee for Unicef, Gilbert Mo, the chairman of fund-raising committee, and Andrew Nathan, the general manager for Starbucks in Hong Kong, kicked off the annual campaign, this year based on the theme of 'Light Up Lives For Children'. On a pop-up stage outside the Fashion Walk mall in Causeway Bay, Koo told the audience that 'by sparing HK$10 from gifts that you're going to buy or spend on festive eating, you help buy 107 water purification tablets, which each provides underprivileged children with five litres of safe drinking water'. Calling Christmas his favourite festival, Koo, an ambassador for the Unicef committee, showed how easy it was to contribute. People can use their Octopus cards on a giant red cup situated outside the mall to donate HK$10 and receive a buy-one, get-one free coupon or free size upgrade in return. The idea finds favour with sweet-toothed Strang, who says she loves Starbucks' gingerbread latte as it reminds her of eating gingerbread with nutmeg when she was younger. So as the days turn nippy, chill out at cafes and help the less fortunate.
