Considering most fast food shops pay reimbursement (not always 100%) and like, what $4-$9 fee, the $12 Strategic Reflections pays gives them HeartsNHugs from me. They don't fart around too much in negotiations because they are fair at the start.
Have you seen their message about their penalization for not completing shops? Yes, I think the person who wrote that message is in charge of the penalization review board and they will hold it against you (or anyone). That said, I would never do their revealed shops for $12 and food. It would have to be $20 - $25 because the Managers and employees do not have a very high turn over around here and that would out me for the non-revealed shops turning my reports into useless mash of "I'm a good-two-shoes when YOU are shopping me because I now know you are the mystery shopper."
