I had wondered about these audits. There is usually plenty sitting on the board but I didn’t know if it was a pain audit or a not so much a pain audit. I learned the hard way on pictures, I no longer order the same sandwiches back to back in a shopping day, but can see how this could be more tedious. Perhaps if you do them in the future you can write the shop number on the top of the brochure with the date, or on a piece of paper above brochure, I know another phone audit required the shop number on business card... might ask.
As for shoppers, when I was 6 months in to shopping I did work for another company I had to drive 200 miles and the elderly staff at the MSC never put the bonus to the shop, so I was dealing with that all while being asked to do another long trip, I told the scheduler I was afraid to take any additional shops until the other got figured out, he said didn’t matter to them because they had thousands of shoppers. So although some schedulers and companies appreciate us, it appears we are more replaceable than we want to think. Which is also why I bust my butt to do my regular shops every month so I am not replaced.
