Fifteen Tangs employees learnt how to guide, approach and make physical contact with visually impaired customers in a collaboration with the Guide Dogs Association for the Blind this week. Yesterday, they practised their skills on five young visually impaired shoppers at the Orchard Road store. The five, aged between 12 and 15, were each given Tangs vouchers worth $150 to spend. Randy Toh (right), 15, who bought a pair of sunglasses, said: "I was walking with the cane, and more people came forward to help. It made me more confident when asking questions."
