CIGARETTE YOURS AND SMOKE OURS WHY

Once Tejpal was travelling by Bangalore Express. It was winter season and all the windows were closed. A young man was sitting before him. The young man started smoking. We all know that smoking is prohibited in trains.
Tejpal asked, “Young man is this cigarette yours?
“Yes surely mine, do you think I am a thief? I have paid Rs. 151- for this packet of Red and White cigarette but why are you asking that?
In a grave tone, Tejpal said, “Why you are distributing smoke with out charges when cigarette is yours and you have paid for it.” The young men felt sorry and threw the cigarette out.
