If Charlotte is skilled at anything, it's recognizing sarcasm. She uses it herself on a daily basis, after all. Even if she didn't, though, the smile her would-be victim is wearing is enough to clue her in to the fact that he isn't actually that upset. Which is great, because the last thing she needs is to get a reputation for antagonizing men at Christmas parties.

"I do actually keep a list of all my victims, so that's very helpful of you, thank you." She extends her hand to shake. "I'm Charlotte."
