One Engineer could not find a job so he opens a clinic and puts a board outside..
"Get treatment for Rs. 300...if not treated get back Rs. 1000"
One Doctor thinks this is a good opportunity to earn Rs. 1000 and goes to clinic.
Doctor : I have lost taste in eating
Engineer : Nurse , bring medicine from box no 22 and put 3 drops in patient's mouth.
Doctor : This is Petrol
Engineer : Congrats.. you got your taste back ..give me Rs. 300
Doctor gets annoyed, goes back after some days to recover his money
Doctor : I have lost my memory, can not remember anything
Engineer : Nurse , bring medicine from box no 22 and put 3 drops in patient's mouth.
Doctor : But this medicine for taste of the tongue
Engineer : congrats. you got your memory back.. give my fees Rs. 300.
