An engineer lost his job and was unemployed for a few months. When he spent all his money, he decided to open up a clinic. He put a sign on the clinic, saying: ‘Treatment $500, but if you do not get better regain $1,000.’
A doctor saw the sign in front of the clinic and decided to earn some money. He went into the clinic and told the engineer that he had lost his taste. Then, the engineer called the nurse and told her to take the medicine from cabinet no. 15 and put two drops of it in the doctor’s mouth.
The doctor yelled and told that it was petrol. The engineer told him that his taste is back and charged him $500.
In a couple of days, the doctor went again to the clinic. He told the engineer that he had lost his memory. Then, the engineer told the nurse to bring the medicine from cabinet no. 15 and put 5 drops of it in the doctor’s mouth.
When the nurse brought the medicine, the doctor said that it was petrol. The engineer told him that his memory is back and charged him $500 again.
After a week, the doctor decided to visit the engineer again and to win some money. He went to the clinic and told the engineer that he had lost his sight. Then, the engineer told him that he has no treatment for his problem and gave him $1,000.
However, the doctor told him that the bill was not $1,000, but $500. The engineer happily told him that his sight is back and charged him $500 again.
