Back in the prior decade, I completed 21 dining assignments for a now defunct MSC named J,C. & Associates. The pro column included I was permitted to dine alone, my fee was all inclusive, I thoroughly enjoyed the food, the report was easy, the shop window seven days and any time the eatery was serving. On the con side for some, but not me, was that the pay took, according to my records approx. 60 days. At that time I was also contracted with BestMark, before they fired me. Their dining reports were miserable, there was not a fee, I was required to pick a specific date, a guest was required and they assigned the meal period. My point is that it is different strokes for different folks.
My last shop for SS paid me $20 + $25 for food. I was NOT required to have a guest and the report was easy. The completion was 2 1/2 mos. ago and I have, as yet, not been paid; that works for me, as the enjoyment of the food and lack of restrictions are of paramount importance to me but certainly might not be for other folks.
Many years ago, a poster on Volition stated the fee amount was not important to her, as long as it was quick; I responded she would be a perfect fit for Trendsource.
