Weyoun is rather (unsurprisingly) cheerful in his reply of, "Oh no, not at all. Thank you for preparing it."

He goes about getting himself a serving and something to drink. "I found you a vocal coach. She's... eccentric, but I think you will get along with her alright." He hopes. Founders, does he hope. "I don't suppose you'd mind if I dined in the, er, dining room? I have a few more calls to make, I'm afraid they'd be rather disruptive to you both."

That might be the Weyoun version of mercy.
