The time that one of my co-worker made me angry was that, we had a work to do for a client which was very urgent and we were to finish it next day very early in the morning. Then my co-worker came very late and the owner of the work came ten minutes later after my co-worker had reported, the client found that the work was not finished and he got furious to me to a point of leaving the work halfway done and he could not pay for the work since I was the one to manage the work . I used my own ways to make him comedown and assured him in the next ten minute the work will be done, the client could not listen but I insisted to him till he finally agreed and settled to see whether I will do what I had promised to him. I did my best and finished in time, he was very happy at the end and left very happy.
