Big shoppin stores are inside a large complex and it is not possible to have so many employees to look over each and every counter in the complex individually . So owners have to find something by which they could look over a large place at once and in this way the mampower required would also be less. So, to attain this need ,they use convex mirrors to watch the activities of the customers . Convex mirror is used as it has a large field of view , hence it allow the shopkeeper to track all the activities inside the store at once and for all.
