Secret Shoppers...well paid amateur spies

If any of you work for a retail or restaurant type of job you have the joy of working with an elite group of taste-testers known as "secret shoppers". They're the reason you have to make sure each and every guest is welcomed into your establishment and properly cared for (aka falsely smiled at and asked if they need anything).
If you are a secret shopper you know that it is pretty much the easiest job in the world...basically you get hired through an agency and they contact you when they want to you shop a place and then you do a short write up about that restaurant or store.
On the flip-side the workers and restaurant receives your evaluation (more getting paid for your opinion...you noble amateur, you!) and then they assess the damage accordingly. As a receiver of many of these evaluations from secret shoppers...they are non-professional, often subjective and very often misspelled and miscounted...in other words--amatuer-ish. The secret shoppers themselves can earn around $40 a shop and keep the stuff they buy or eat.
As a worker...often you can receive incentives for being a good little secret shopper pleaser. For instance I have received many pins and stickers for appeasing the everyday professional amateur and bringing them refills on time or folding tens of thousands of child-sized blue jeans at the mall...it's an amazing program...really. Yes, I got to keep the pins...but I did not receive $40 and secret shoppers don't always tip well.
Instead of having corporate come in and evaluate a store or restaurant these "spies" use their own unique knowledge to assess their opinions, and then send them to a company so that they can have an outsiders view of their service.
