They monitor you when you made some deposits in the bank.
They sit you down and start asking questions when you are ready to use your hard earned money.
They use your money behind your back to invest for themselves.
Did you know banks could be funny at times! Most of the times I attend the bank for some financial activity, like 8 out of 10 times I observed that there is always uninterrupted available network for depositors and the queues move fast unlike when it comes to withdrawal you will be experiencing network issues with their ATM's that ends up delaying the customers from withdrawing, and I have come to an understanding that it is a deliberate act to deter customers from taken their money from their confines so they don't lack fund to give out for loans, or investments for their own benefit while the customers that owns this money don't even get an interest added into their individual account at the end of the month.
The banks through the government can do anything possible to bar customers from withdrawing their money especially when withdrawal is starting to exceed deposition.
