You are correct. I even had one IPSOS scheduler offer me an increased rate for "fill-in" shops (gas stations), because my route for the primary 'bonused shops' made the "fill-in" shops convenient...then the primary 'bonused shops' were removed, and I had to cancel most of the "fill-in" shops. The email from the scheduler promised a specific pay rate (which she had to seek approval for, and received that approval)....then the rug was pulled out, and the scheduler said, and I loosely quote her, "...oops, sorry, you never know." Another reason not to trust Ipsos.
