Probably the MF red/orange stations. Those shops used to all be audits, as far as I know, and then they tried out the simpler mystery shop format. I agree the audits are waaay more complicated, especially at first. Think 40 pages of guidelines. These shops will go up to $35 on the board if no one takes them, so the fee does get reasonable. But as long as someone is willing to them for $7 and gas, it makes sense from MF's point of view to start them out low.
