Once a female customer in my pharmacy asked me to recommend a drug that she could use to poison her husband.
I replied, “Ma’am, not only will I not respond to you about that, I’m going to call the police and advise them that you asked me that question.”
She then reached into her purse and handed me a picture of her husband having sex with my wife.
I looked at it and said, “Oh, you didn’t tell me that you had a prescription.”
