Okay...i'm clueless to you.
I choose not to do that assignment. There is a regular BWW dining assignment from the too many men MSC where the report is much easier and I can eat without the hassles of the detail required for the bar audit.
People must be doing it FOR THE MONEY. If it's for the food, you get an easier shop for the dining scenario.
I've done a "bar audit" at an upscale hotel for another MSC. I do not drink that much and i got paid $40 to sit there for an hour and pay attention. After I did it, I thought...Why did I waste my time doing this? I don't need the alcohol. I don't need the $40 and would rather spend my time doing easier assignments. I could do 3 pandas and make $24 (base pay) and spend half as much time and actually feed people in the process.
