I know of folks who work with them and are pleased enough with the audits. They have different methodologies for working with the amount of data to be collected. One was mentioning taking a photo of the menu board to be able to do all the data entry at home from the pictures. Not quite sure how they pull that off. I have not taken these jobs because the eyesight is not wonderful enough to read the menu board to take notes from a table close to the order area.
I have heard no complaints about late or short payments or excessive pickiness.
