While she definitely seemed promiscuous, Castiel felt the need to clarify that. He'd seen a real "hooker" as she put it once. And she hadn't shared her saliva either. She had mostly tried to remove his clothing and he'd remained frozen while trying to think of something to say to her.
Just as soon as he'd made that statement however, the still somewhat damp waitress was on her way back to the table. She more or less threw the food at them. Judging from the way the plates hit the table, she was understandably unhappy.
Once she'd left, Cas was left to stare blankly at the food. "These are softer than Dean's."
