In what ways is a hawker different from a shop owner?
A hawker provides door to door service. He sells his goods by calling out the names of his items. He generally owns a thela which we may call a movable shop and keep in it different items of our everyday use. He sells his goods at the minimum profit.
A shop owner runs his shop at one fixed place. Whenever we need anything we go there and purchase it. Here, we get things at the somewhat costlier rate.
