Selling on the road is very common in Nigeria where they don't collect shop or stall to sell thire product. This is an example of a puff-puff seller who make alot of money just by making Puff-puff on the road side.
He make use of gas cylinder and a big frying pan. People who do not cook that feel like eating snacks buys from this person. It is really a lucrative business in Nigeria and people are venturing into it.

Thanks
