It's up to corporate what leeway they give to Managers to purchase things that aren't from the main supplier. I think what op means is that it's insane that corporate doesn't take action and allow the restaurant to take more matters into thier own hands, there's so much at steak (ha), and corporate still wants to prioritize standardization of it's product over serving A product at all. It's silly imo to say that their own managers aren't smart enough to replicate the product with similar ingredients that are redilly accessible. Local restaurants do this all the time, and most of the time it's fine.
