Earlier quoted context omitted.
That is how India rolls. I am not sure how the poor street food vendors survive if they cant use plastic plates and spoons. If they are forced to use steel plates and spoons that is a health and safety nightmare in India.
There are plenty of cost effective traditional alternatives. Banana leaves, hand made leaf plates, machine made leaf plates, in the worst case paper plates. Plastics are just convenient and cheap, if the environmental costs are not considered. Edible cutlery http://www.bakeys.com/
I have normally seen steel plates/spoon used by street vendors. Not very hygienic as they just rinse in water after use.
