"Yes, I am the waiter-help and I am making one thousand dollars a glass so please, yes, drink another and slam it down like an animal would.

"I'm serving drinks, Sherlock. You could play nice with your brother by taking him one. Or can the fallen only gaze at those above them and not approach?" Caleb turned away, handing a drink out to a shy intermediate. "Enjoy the dance," he said to the young girl, appreciating her nod of thanks before she turned on her heel and tried to get away as fast as possible.
