An ATM Machine

Before I start, please promise you'll not grin
As this story takes me to an ATM machine
Much heard of, but never seen
A need never arose to have been
Until her hubby had to go away
for days fifteen, who dealt with
all the money matters, saving her
from daily clatters, who never knew
this episode will send her poised
life into a different spin..
Ah! it was September, the sixth
and her son was in the standard fifth
An urgent spending to be dealt with
took her to the nearest ATM,
A vacant space, no queue seen there,
what a blithe..
She soon followed the successive
instructions that popped on the screen
After putting the sim card into the space
it should have been,
the waited (what seemed endless) for money
to come out of the machine,
till she heard a resonating sound 
and to her dismay,
the notes instead of coming out were
returning into the machine!
She tried to snatch those paper currencies
but to have a tug-of-war was futile;
So, she let them go, came outside the box
with a receipt of five thousand bucks
she was supposed to withdraw!
It was another blunder added to her
already huge list which she will never be

able to disclose a bit!!!!
