I am totally intrigued by mistery shopping

I recently read about a practice called mystery shopping.Wikipedia defines it as a " tool used externally by market research companies or watchdog organizations or internally by companies themselves to measure quality of service or compliance to regulation, or to gather specific information about products and services.
The mystery consumer's specific identity is generally not known by the establishment being evaluated. Mystery shoppers perform specific tasks such as purchasing a product, asking questions, registering complaints or behaving in a certain way, and then provide detailed reports or feedback about their experiences.
Tools used for mystery shopping assessments range from simple questionnaires to complete audio and video recordings. Mystery shopping can be used in any industry, with the most common venues being retail stores, hotels, movie theaters, restaurants, fast food chains, banks, gas stations, car dealerships, apartments, health clubs and health care facilities. "

I mean ..can you imagine anything better than going shopping, being paid to do that and evaluate your shopping experience?
In the US mistery shopping has an association, the Mystery Shopping Providers Association (MSPA) and it seems that even in Italy some companies are currently recruiting people to become mystery shoppers..
So..what are you waiting for? apply, apply, apply...:)
