Walking around the tables at fast-food outlets, one cannot help but notice the amount of french fries left unconsumed.

With the recent call to rein in food waste, I challenge fast-food outlets to serve smaller quantities of fries to customers.

Perhaps these outlets could start a new campaign where customers can ask to downsize their fries and 30 cents would be donated to charity.

This costs customers nothing, but may give them better health, as they consume fewer unnecessary calories.

Less fries would be thrown away, and fast-food outlets can save by cutting down on the amount of fries they buy, as well as the oil to fry them in.

They also benefit from a boost to their social responsibility image.
