"Karen, I'm at work right now," he said with the gentle patience of a parent speaking to a child. "Maybe when we're done here we can explore your ideas for a fun evening, but..."
Suddenly, peanut butter met jelly. He paused, and regarded her warily, now. "When you say you want a drink, you're not talking about out of a glass, are you?" He really should have seen it. She was a vampire - or something like it - who liked her blood flavored with a little spike of something extra.
Oh well. Nobody's perfect.
"I'll see what I can cook up for you when we're done here." She didn't seem evil - well, okay, not intentionally malevolent, anyway - so he figured it was in everyone's best interest if he fixed her up with a steady supply of blood that wouldn't hurt anyone.
He resumed his parental manner, grabbing her shoulders. "You be good, now, okay?" He kissed the top of her head, patted her cheek, and headed into the crowd again.
