7 hours later at Narita International Airport, Tokyo. Had no idea that DFS items bought in Singapore, sealed and with proof of receipt are not allowed on board transit flights. The Japanese lady at the security scan area was so hostile and wanted to cut open the see-through bag. I refused to let her do so and eventually spoke to a much nicer man from the information counter who advised me to run and have the items checked in. Either there should be some kind of international understanding for DFS-bought items or Singapore Changi Airport Nuance-Watson staff should have advised me, otherwise it would have been S$400+ worth of products gone! I wouldn't have been too happy with that.
