An Engineer could not find a job, so he opens a clinic, and puts a sign outside that says get treatment for $50, if not cured get back $100.
A Doctor thinks this is a good opportunity to show up the engineer and earn a quick $100. And so he visits the clinic.
Doctor: I have lost my sense of taste.
Engineer: Nurse , bring the medicine from box no 22 and place 3 drops in the patient's mouth.
Patient (Doctor): Spits out the medicine and says "This is not medicine, it's Gasoline".
Engineer: Congrats.. you have your taste back ..that will be $50
Doctor gets annoyed, and returns after several days to recover his money.
Doctor : I have lost my memory and can't remember a thing.
Engineer : Nurse , bring medicine from box no 22 and put 3 drops in patient's mouth.
Doctor: "This medicine is for the sense of taste" protests the Doctor.
Engineer : congrats. your memory is back.. ..that will be $50
Doctor leaves, but after several days angrily returns for one last try.
Doctor : My eyesight has become weak.
Engineer : Well I don't have any medicine for that. Take this $100
Doctor : But this is $50 Note
Engineer : Congratulations, your eyesight has gotten better. ..that will be $50
