Context: I'm an academic, and I often apply for grants in my home country. Its a tedious work, and the application has to prove that I am capable to finish the project I propose, not only at scientific level, but at management and accounting level. After passing successfully the evaluation process, a whole different process starts. It consists in you interacting with the grant agency. The grant agency assigns you a manager who makes sure your paperwork is in order. She (it's usually a she) has a very short fuse and seems hell bent on making your life miserable. To use a metaphor, it feels like you are a famished beggar and when you beg someone for food, they throw a half eaten chicken wing on the floor and then they tell you vanish because you're disgusting. In my case, the chicken wing is my slashed budget.
So, what would be a proper idiom, or expression to describe the process by which someone answers a request in a most humiliating, condescending manner?
