Flag-day hours are being extended on a trial basis beginning today in the hope that charities will be able to raise more money. Instead of ending at noon, volunteers may continue seeking donations from the public until 2pm, possibly cashing in on the after-work generosity of those who work a half day on Saturdays. The Hong Kong Society for the Deaf, one of the groups that will benefit from the extended hours, is cautiously optimistic that the change will enable it to raise more funds. 'We hope we'll be able to raise more money but have been encountering difficulty in recruiting volunteers, who probably don't expect to have to help out in the afternoon too,' Maggie Man Suet-yung, service co-ordinator for the group, said. 'I'm not sure that they won't decide to just start later than the 8am starting time and then work till 2pm, in which case it will make it just the same.'
