When I was working in a call centre, I used to find it funny how some people used to wear their Id's in trains, buses etcetra to show off that they worked for "big shot Z biz " to the normal public. In most of the cases, these normal public are not even aware of such a company's existence or care a hoot. The irony is: These same "show offers"(new word) often chose to keep their id's hidden where it was mandatory at their work and show it off where it's completely useless. A mystery shopper knows exactly what I am saying here!
My point is: If you're a Mystery shopper or a Ninja, this pendant can serve as such id. Ofcourse, please don't wear it at the place of audit or where you don't want to be discovered. Ha Ha Ha, I said it. There. You get my point. Think it, believe it, show it with pride!
