I have a feeling they designated so much per category. Their online - to go, food truck style, and then seated customers. On a crazy day like that, their usual operating methods are thrown a curveball. They sell as many that one day as pretty much the rest of the summer combined. It is their Black Friday, their Super Bowl. My bro with the inside info just confirmed they leave a small buffer for the seated diners. Makes sense as they are likelier to spend more in regards to apps, beverages, and dessert. Which also factors into tips. Online and food truck tips just don't get the same percentage.
That doesn't surprise me. It's an up scale cafeteria style operation. It's never great but it's always edible.
