An engineer was unemployed for a long time. He could not find a job so he openned a medical clinic and put a sign up outside: “Get your treatment for $500, if not treated get back $1000”.
One doctor thinks it’s a good oppotunity to earn $1000 and go to clinic. Doctor: “I have lost taste my mouth”
Engineer: “Nurse, Please bring medicine from box 22 and put three drop in the patient’s mouth”
Doctor: “This is Gasoline”
Engineer:“Congratulation!!, you’ve got your taste back. That’ll be $500”
The doctor gets annoyed and get back after a couple of days to recover his money.
Doctor: ” I have lost my memory, I can’t remember anything”
Enginner: ” Nurse, please bring medicine from box 22 and put 3 drops in the patient’s mouth”
Doctor: ” But It’s gasoline”
Engineer: ” “Congratulations! You’ve got your memory back. That will be $500.”
The Doctor leaves angrily and comes back after several more days.
Doctor: “My eyesight has become weak.”
Engineer: “Well, I don’t have any medicine for this. Take this $1,000.”
Doctor: “But this is $500…”
Engineer: “Congratulations! You got your vision back! That will be $500.”
