When a thief forces you to take money from the ATM, do not argue or resist. You might not know what he or she might do to you.
What you should do is to punch your PIN in the reverse mode. I.e. if your PIN # is 1254, you punch 4521.
The moment you punch in the reverse mode, the money will come out, but will be stuck into the machine half way out and it will alert the Police (security) without the notice of the thief.
Every ATM has it; it is specially made to signify danger and help.
Not everyone is aware of this.
