Miss X is from

years old now and she became a mystery shopper.
Mystery shoppers are people who get paid to visit shops and pretend they are regular
Their job is to assess the quality of service in shops, for example, how
the shop is and if the shop assistants are
Sometimes they also
write easy of the products they have bought. Mystery shoppers don't usually earn very much, and
not all shopping experiences are pleasant. Once Miss X had problems with a product which she
bought information. It's not difficult to become a mystery shopper, but you have to be a few
timesbecause some companies are fake and might send you a lot of once or twice messages.
