In 2008 & 2009, I was regularly completing Applebee's assignments for a now defunct MSC. I was paid a flat $25, from which I deducted my meal costs, leaving me with approx. $13; how sweet it was, until I screwed up and didn't notice a change in requirements after 40 or so shops. I selected 4 locations before noticing they were now age verification jobs. As this MSC was also providing me with Red Robin and Abuelo's work, I "bite the bullet" and arranged to pick-up a young man to accompany me; it was a definite pain and cost me my fee, but taught me a lesson to not assume that all is a constant.
My recommendation for the OP is to "grin and bear it." Not only from a business, but also personal, standpoint it's the correct decision.
