it's a disposable chef's cap to keep hair out of food similar to a hair net, hair nets seem more effective so i think it's just kinda a part of the branding at this point
Well you see it’s much like the Crown at Burger King where if you go and are around the counter for extended periods of time they want you to stand out. Also kind of like a dunce cap.
More accurately for Waffle House it means they have knuckle sandwiches ready to serve all customers at any hour
