People are using ATM these days to that extent that no booth is left uncrowded.And of course it is better to use it and withdraw amount when in need instead of keeping lots of cash with you.But while using we should be careful with some points. At times it happens that because of long waiting line one feels awkward to be slow when your turns come and we left the booth just by collecting the cash and your transaction is not still closed. In such case it will be very easier for next person to continue with your transaction.so all such things should be kept in mind so as to avoid mishandling.
