Some people are upset because they cannot withdraw less than $50.
Furniture consultant Shah Pakri, 40, who likes to withdraw $20 at a time found that the two nearest ATMs to his home only dispense $50.
It turns out, those particular ATMs were among some 275 DBS/POSB ATMs which were reconfigured last October to dispense only $50 notes.
Said Mr Shah: "It’s ironic that POSB, which is supposed to be the people’s bank, is inconveniencing low-income earners."
Others, like safety co-ordinator Francis Teo, 44, felt the new configuration helped shorten the waiting time for customers who wanted to withdraw large amounts.
He said: "The queues for such machines tend to be shorter."
A DBS bank spokesman explained that the ATMs were reconfigured because of the withdrawal patterns of its customers.
