A Gujrati opened a clinic & wrote outside the clinic

A Gujrati opened a clinic & wrote outside the clinic: Any treatment in Rs.
100 & if we cant treat, will pay back you Rs.
200.
A Pathan comes to do fraud & get 200.
He says to the Doctor: I cant feel any taste on my tongue.
.
.
Doctor asks the Nurse to put few drops of medicine from box no 22.
After that the Pathan shouts: Oh my God its very Bitter The doctor says congratulations your sense of taste is back now.
The Pathan was angry as he lost Rs.
100.
After 2 weeks Pathan comes back again & this time he thinks to get back his prevoius 100 too.
Pathan: Doctor i have lost my memory.
Doctor: Nurse! pls put some drops of medicine from Box no 22 on his tongue.
Pathan: Wait doctor but that medicine is for sense of taste.
Doctor: Congratulations your memory is back.
Moral: Never think to cheat a Gujrati.
