SINGAPORE: Attending to his customers, Mr Chieng Puay Chui and his ice-cream cart have been a familiar sight along Orchard Road for about three decades. The 71-year-old, more commonly known as Uncle Chieng to his customers, has been an ice-cream street hawker since 1965. About 30 years ago, he decided to start selling ice-cream along Orchard Road outside the old Tangs building, and moved to his current spot in front of Ngee Ann City when it opened 26 years ago.  But his ice-cream cart and six others along the stretch of shopping street could become a memory when their licence holders pass on. Street hawkers like Mr Chieng hold licences that are personal to the holder and non-transferable, said the Singapore Food Agency (SFA). “It’ll be a pity if there are no more ice-cream uncles, especially because this is Singapore’s traditional ice-cream,” said Mr Chieng in Mandarin. “I don’t know if anything will be done to make sure Orchard Road will still have ice-cream uncles in the future.” Mr Chieng is among 13 street hawkers allowed to sell ice-cream on any “public land”, according to SFA, with seven choosing to operate along Orchard Road.
