An Innovative way for avoiding plastic bags !!!

I read this in a local newspaper and thought of sharing it. A meat shop owner in Tamilnadu always cares for the environment and wanted to get rid of plastic bags. So he started a scheme and told his customers that if they bring vessels for getting meat,he will offer discount of Rs.2 on the price. There was only little response from the customers.Then he increased the discount to Rs.4.Still not big improvement.Then he offered 2 to 4 eggs free of cost if they bring their own vessels.This offer clicked and many people are now bringing their own vessels.

If a small shopkeeper can think like this, why don't the big supermarkets may think of some idea to get rid of plastic bags?
