Let’s be very careful while at the atm stand, not everybody seen at the atm machines want to widraw money some came for there fraudulent activities, don't call anybody to assist you except the security personnel working in the banks.
I don't think many Nigerians still make use of ATM machines or stand because of the probability of not finding cash in them when you need it the most. Many Nigerians have moved to using POS outlets where you are more certain that you can get the cash you need for a specific charge. So for this advice I think we should be more careful and know that the people or the attendants at POS outlets are not our friends.
