Sorry - but what is exactly the argument that you are making?

Is the way the hospital is currently doing it not cost competitive?
If that is the case, at which point of the process would the "big boy" be more competitive and why?
If a "big boy" would be more competitive, why is the hospital not switching?

BTW, I am not sure to which extent a hospital canteen (that is obviously not just preparing lunch and where meals are not just served centrally in the cafeteria) is comparable to a school or a canteen of a company
