In this concept, you have to become a secret agent of the company & try different products of the company at their outlets.
Here you have to check your experience as a client & submit your feedback to the company.
e.g. Raymond wants to know, what treatment their customers get, when they go for shopping at their outlet in a particular city.
Or a chain of hotels want to know, how their customers feel while they stay at their hotels.
You have to actually shop or stay at hotels & all the expenses are provided by the company. You will get paid for sharing your experience.
