Do you know that banking institutions is still in business because of the late payments by people like us. If everybody pays within the schedule, they are still making money by the interest rate fixed by them and agreed by debtors. But the real money business that make them richer and happier is when debtors pay late. There is where the interest become higher and debtors will suffer from the increasing rate. The money you need to pay may become double, triple or higher than you could imagine.
This is the most correct description about Bank. There is the devil hiding behind them when you sign your agreement. The evil terms and condition clearly stated on your agreement letter but you can't read it because it's too small or it's too long too read and you don't have time for it. Usually , the bank officer will wait in no time asking you to drop your signature and read the terms later. You will have no choice unless to follow their most evil terms and fucking regulations.
