Putting The Right Amount Of Food In A Fast-Food Bag

At home, while eating a chili dog topped with raw diced onions that I purchased at Checkers, a fast-food chain, I noticed that on the bottom of the bag were three illustrated panels in red in the shape of a paper bag. Each panel showed the kitchen staff how many of what items would fit inside the bag. I've never seen such illustrations on take-out bags at any other fast-food restaurant. The first panel shows that four hamburgers and a container of fries will fit in the bag; the second panel shows that four hamburgers and two containers of fries will fit; and the third panel shows two hamburgers, a container of fries, and one chicken strips/fry box. I assume most customers at Checkers are too focused on their order to give much attention to these illustrations. To me these illustrations are a good idea because they are a guide for the staff to follow to prevent them from putting too many hamburgers and/or fries in a particular size bag.
