Smoking in public place in front of little child.

Nonsense Activities in Layelka [tollygunge.south kolkata]
The young couple seated just behind of little child [son of my sister-in-law].
Repeatedly request to blue shirt boy don't smoke near child.
He and his girl friend told me that " where written it is no smoking zone" and give pose to my camera shamelessly.
Making video of my protest so kindly humble request to administration please look into this matter so all this nonsense activities like smoking in public place strictly prohibited.
