I was assigned 9. I did other drive-thru audits for them and loved it. This was different, and "timing is the most important part of the project." Very time consuming, and reporting should have been easy, but wasn't, apparently. Have to park and observe another vehicle. Yes, your food comes out of your 15 -- must purchase entree, side and drink. The only way to make somewhat of a profit is to get kids meals. Every "special request" is supposed to be different; not easy at the Asian place. They did not get back to me for two weeks after I submitted reports (soon after I left for vacation).
The video instructions are clear, but if you report that way, they will keep sending it back to you asking you to change the times. (If they want it changed, and I don't want to lie, I don't know why they don't just change it themselves.)
So, my advice if you want to do it for the meal: Go early; Eat while you work on the second half; Try one before you sign up for more; Plan on being available for two to three weeks after you submit your reports; Be prepared to fudge. Just my $.02.
