I actually had the same thing happen during my last appointment with a provider (review coming soon).

We ended up getting a late start due to a couple of minor issues.  Once we got going, it was a very enjoyable romp.  She had me at the point where I was basically putty in her hand ... or, umm ... actually mouth, when her phone so inopportunely started ringing.

I guess she had a different ring programmed for her safe call, as in, "If you don't answer this call, I know things are going bad and I will send in the calvary."
She said to me, "I am REALLY sorry, but I HAVE to get this."
Jumped off of me, ran to get the phone, basically blurted out, "Everything's great.  I'll call back when I'm done," ran back into the room, jumped on the bed, and pounced on me again before I could even think of losing arousal.

Actually was great session.

Another time, I was with a very highly regarded lady.  Her phone rang at least 5 times during the 1 hour appointment.  She answered it every time after saying, "My dad is having some medical issues, so I need to get this."

While I can appreciate the need for staying informed, all I could think was, "Don't take appointments if you have something like this going on at the time of the appointment."

I would have MUCH preferred if she had cancelled altogether.  Nice lady, but the session was basically ruined.

Footnote:  Couldn't review her since her ad disappeared before I could submit a review.  She resurfaced months latter.  Too late for my review to count.

BTW, Fuzzy, funny picture as always.
