If you performed two food shops for Market Force, during the same meal period, they are going to reject the second one if you submit it. When they called you, the scheduler would have stated this during the call. It is our responsibility to know if we have another FF/FC shop with them during the same meal period.
By the way, MF does not tell us to NOT eat the entire meal. Like most MSCs, we are required to at minimum taste the food.
