Chemist and Beautiful Girl

A beautiful hot looking girl in a short skirt was standing outside a Chemist shop
She was definitely waiting for the crowd to disperse whilst the shop owner spotted her waiting and got suspicious.
After 20 minutes there was no customer in the shop and she was all alone, then she entered and walked straight to the counter…
She made sign language to a salesman and called him near her
The shop owner further got alert and suspicious by now. He was eager to see her requirement.
She sneaked her hand in a purse and pulled out a hand written paper directing it to the salesman and whispered…
“Bro, I am soon getting married to a doctor, this is his first letter to me can you please read it out?”
