A 19 year old boy went to wine shop to have some beer. He asked the waiter " how much a Brand X beer costs?"
Waiter replied, "Sir, It will cost Rs 75."
The boy started counting how much he had in his purse. Then he again asked how much a Brand Y beer costs??
Now Waiter got irritated and replied "Rs 72".
The boy had a Brand Y beer and after finishing his drink he paid the bill and left.
When the waiter came to pick the empty bottle..., He was touched........... !!
The boy had left Rs 3 as tip for him........!!
