Often times we have all witnessed "Shradhhalus" ( devout) holding road side langars ( community free food distribution) on religious occasions such as Durgaashtmi, Navmi, some Jayanti or just for thanks-giving to your favourite Deity for prayers answered. 
While I have high regard for people who take time and money out for service of humanity, to feed the poor or not-so-poor, what they leave behind on pack-up is a greater dis-service to mankind than anything else! Plastic plates, spoons, styrofoam glasses, fly-away carry bags of 5 micron or even less thickness all lie strewn on pavements where the langar was held, waiting for some municipal worker to come and clear it.
Today on this day of Durgaashtami, Gandhi/Shastri Jayanti and on launch of Swachh Bharat campaign, let us appeal to all religious and community organisations to specifically avoid leaving litter behind while they serve humanity by holding free kitchens ! Use the traditional degradable Doña-Patta-kulhar for serving and take them with you when you leave!
Amen!
