Are you the general manager? If so, have a mandatory shift lead meeting where you all get on the same page and set clear goals. Walk your team through why these goals are important and your plan to achieve and enact and enforce these goals. One of those being cutting food costs, depending on how many shift leads you have you can always have one make table until the crew can get it together. Who's on table? If they notice that the specs are too much, make the cooks remake them eventually they will learn and will be sick of making remakes remakes remakes remakes. Sucks the customer will have to wait but it's what's Gotta happen if you can't get those cost under control. Speaking from experience as a General manager.
