Lol. Let me share my experience with OLD UPGRADED Ticket
Machine.
I wanted to top up my EZ-Link card (I always use the machine
to). I insert a $2, no problem.
I insert another $2. Whoops. The whole machine hang and it ate
my $4. I go tell the staff. =.=
He go reverse out the $$. He only managed to reverse out $2
while the other $2 was already inside the machine.
He asked me follow him awhile then he give me $2, ask me to sign
here write my name, bc number all those stuffs. Then he give me the
$2 it eaten. =.=
Then i go to the person top up $5 lol.
Next time. I'm not gonna top up at stations between Yio Chu Kang
to Toa Payoh. Dangerous ar beware
