The ability to prioritize cooking, currently if i have two bills, in any order, cooks will randomly choose, i have a 3 star chef and a 10 star chef so my stove needs to have two bills, one for fine, and one for simple, then my 10 star chef gets lazy and cooks a simple meal instead of a fine.
Alternatively scrap the the bill, and just make it so the chefs will cook the best meal they can possibly cook, this way my 3 star chef who is can't do anything bar research and cook, can actually acheive something without my 10 star chef creating bad food.
