They can limit how many you perform for their MSC for a particular day all they want (Market Force does this with their fast food shops in that they say you can only do one FF per meal period).
However, they cannot limit how many you do with other MSC's.
You could do the one Market Force breakfast shop and four (or as many as you want) FF breakfast shops from another company if you think you can get them all done in the time allowed.
Shopping across Indiana but mostly around Indianapolis.
