Relieved that she hadn't misinterpreted his joke and slightly disarmed by her later comment, Marcus finished his soup and set down his spoon as well. "We can come back anytime," he replied, choosing his words carefully.
Thomas came back to collect their plates, mouthing something to Marcus that he didn't catch and disappearing again. A minute later, he came back bearing two plates with a slice of chocolate gateau on each, a dessert that they hadn't ordered. Marcus was about to protest, but Thomas cut him off. "A dessert for the Lord and Lady, requested by Lord Marcus as a surprise."
Marcus immediately saw what he was trying to do, and played along. "Thank you, Thomas." Thomas nodded and smiled, mouthing 'It's on the house' to him before returning inside.
