Are you considering making it so there's a way to disable/re-enable certain toppings or food items? Possibly up above the food shelf there's a menu that before the day starts you select what will be for order that part of the day?
There is already a way to disable toppings in the game in case you weren't aware! Just click the toppings you want to disable before you start your shift. As for the food items, once they're added they're on the menu for anyone to order
