Unless you're in a heavily-shopped area, the fees do go up. I'll occasionally do a $15 if I really want lunch and I'm passing by anyway. Also bear in mind the current reimbursement is unlikely to cover more than the basics. That said, the MSC is quite reasonable in their requests and consistent with payment. It's a good shop for getting up to speed.
Things to keep in mind:
* Note what the cashier looks like. Including approximate age, hair color, height, and shirt color.
* Start a timer when you get your receipt. Stop it when you get your food. I delay about 10 seconds each end to ensure I'm not spotted.
* While you're waiting for your food, watch the kitchen. Specifically how clean it is, how many times the fry cook shakes the basket before dumping it, and whether the grill cook changes their gloves after raw patties. (They frequently do a small shake on the fries then put it back in. That doesn't count.)
* Visit the restroom.
* Observe cleanliness, including smudged windows and doors.
And then while you're eating your food, note the quality. Firm but not crispy fries. Juicy but cooked burger, with some toasting on the bun.
The report is a bunch of yes/no questions, a few ratings, and I think 5 narratives of around 200 characters each. The only photo is of the receipt.
