Tea, snacks and a lesson

Ahead of the festive season, the fire service directorate in Patna has come up with a novel idea to educate city residents on fire safety measures. It has decided to invite them for morning tea and snacks. During the gathering, they would be apprised of ways to prevent fire from breaking out and measures to be taken in case it does. Why the tea and snacks? The logic is this: If you call people over for a meeting, they will simply pass it over. But when you invite them for tea, they feel obliged to accept the offer.
