iirc, POSB atm machines are quite dumb
after u press here press there until the part where u can cash
withdrawal of your desired amount, u press $40, they have the
msg
"this machine is unable to dispense $10, withdraw $50 ai
mai?"
in the first place shd let us know there is no more $10 notes
mah
press all the way till last stage then say no more $10
quite weird lah
They pai say to tell you run out of $10 liao.
The machine po you draw $50 or $100 so it can diam diam dun tell
ppl it ran out $10.
