我查了一下，在国外的ATM上取钱会收个overseas withdrawal fee
DBS/POSB and UOB: $5 (POSB某些东南亚国家的特定银行取款机上是$2)
OCBC: (1) Nominal service charge of 3% is levied on the S$ equivalent of the amount withdrawn (min S$5 and max S$20 per transaction) (2) Administrative fee of 1.8% of the foreign currency transaction
Standard Chartered: 2% of amount withdrawn Min. S$5, Max. S$60
