I know a story of a man who likes to constantly complain, he basically complains about everything that happens around him, he has no reference for changes in life.
Even when you give him what he wants, he still sees something to complain about, people do not like to work for him because of his constant attitude of complaints, no matter how skilled a person claims to be in his chosen field, the man will complain about the work done.
There is an artist who was the best person in town and he was summoned to come design something for the man's company, when the board of trustees saw the design, they clapped for him they were so glad he could make something as beautiful as that, but when the man who complains came around, he saw a fault in the design and he asked the man to go and do it all over again.
His family members got really tired of him and they did not know what to do with him again as they have spoken to him and pleaded with him on several occasions to change but everything had proven abortive.
One day he had a major business partner and if the man should withdraw his money from his company, that will just be the end, when the rich man heard about his usual habit of complaining, he decided to teach him a lesson.
The rich man went to his office and when he was offered a seat, the rich man began to complain about the chair the paintings of the office, he complained about everything all through the meeting and even threatened to withdraw his fund, he was really scared.
He went home and he kept on thinking, he knew he was finished if this rich man should withdraw his support, but his wife advised him to call the man and plead with him, he should ask as well if he has done anything wrong to him.
After the man had cried and begged for a week, the rich man told him that he only wanted him to have a taste of how people feel whenever he complains constantly.
The man apologized and promised never to complain unnecessarily ever again.
