A woman goes to a medical store and asks the pharmacist for some cyanide to kill her husband.
The pharmacist is apalled and refuses.
She takes out something from her purse and shows him.
He says " Oh ! I didn't know you had a prescription. Here take it " .
What did the lady take out from her purse.
No full proof answer for this but 1 of the answer i received seems logical :
The lady took the photo of husband with the wife of the chemist in a compromising position.
