It doesn’t take that long to cook more meat as long as the grills haven’t been taken down for cleaning. During rush hour they are doing way more volume than that, it’s just the staging cabinets are in between someone who is cooking meat and someone who is assembling product. Chicken nuggets and chicken paddies are much slower to cook, 4 minutes or so rather than 30 seconds it takes to cook a run of 10 to 1 meat.
