From his position, the way she leaned back and crossed her arms, looking at him as if she was trying to determine if he was worth it, his jaw dropped playfully. He looked mildly offended and just shook his head. He gestured to himself up and down, showcasing his torso and face as if he were Vanna White.
She wasn't turning away or acting disgusted, though, so maybe he had a shot. He picked up his drink and shook it at her, there were only a couple ice cubes in the bottom now. It was sort of unclear as to if he was asking her to buy him another or if he was asking if she wanted another of whatever she was having.
Regardless, he was teasing her back, playing her game.
