Absolutely, tell.
When? As soon as you've got past the "Can I get you a glass of wine? Aren't these canap?s delicious?" part of the conversation.
I wouldn't even dream of putting myself in such a situation, and I think I'm pretty liberal and of the "Just f..k it!" mindset, but this is both dodgy ethically and potentially dangerous for the CD/trans-person involved. Proceed with extreme caution
