What is the right thing to do. You have planned a session with your ATF  some time back but you are now  in the last fews days of a bad cold. You have seen each other in the past when one or both of you has had a cold.  Should you cancel, disclose your cold to  her and ask herpreference or load up with your favorite cold remedies and make the most of it.

If you are still pretty sick tell her. You said that you have seen each other before with a cold,
so if you are not to sick go see her.

cancel.

Thank you and everyone else who responded for your thoughtful advice

I would call her and cancel and tell her that it was because I have this very bad cold and I don't want to give it to her....this gal has to make money----why make her as miserable as you are/have been?

Full disclosure is a good option. Tell her what is going on and let her decided whether or not to go forward with the appointment. As well as if she were sick she should notify you and give you that choice. Just my opinion.

That's the right thing to do regardless. And if she's your ATF, it shouldn't be a big deal.

+1..

Honesty is the best policy when you get sick.  I always let her know ASAP and explain the situation and cancel my appointment.  I don't want to pass my bugs along to my provider and get her sick which could affect her business.  

...#1 I personally don't want to make someone else sick. #2 That's just basic escort-client protocol.  Show up clean, healthy, sober and on time.
