[Sebastian tilts his head slightly to the side, smile remaining the same.]
Thank you for no offer, but I do not think that will be necessary. [Sebastian wants to do the dishes. Because if they're not done perfectly he'll just be annoyed. He'll be annoyed about having to do all these dishes on his own, especially this many, but that's par for the course for Sebastian, so.
At least he puts the knife down. Laughs lightly.]
A chocolate mousse cake will perhaps do for a start, then? [As it happens Sebastian has made a couple of those. He can waste them on a customers hat obviously doesn't care what goes into his mouth. In fact he's not waiting for a reply - just starts preparing a plate with a cake slice.]
