Worst plumber:

Many people think that what they think is only correct.They do not realize the truth and they remain stubborn and do not hear the advice and ideas given by others.The final outcome is that he gets affected by it by irritating others.
The same case happened during the construction of my house.The plumber who we selected had a belief that what he thinks is only correct and others or wrong.My dad told him a lot of times to change the position of the motor.But he said that the position was correct and did not hear to anyone.Finally now after the work is completed the motor did not work well.My dad called him up and scolded him like anything.So friends try to learn your mistakes.
