How do you know it was at the expense of another client!?
I have no idea when T sees other clients.
But I agree with sorry oozit, At the expense of another client isn't professional.
My T has in the past offered to accompany me to a Dr. But she would have done it in her own time.
I'm sure your pretty excited at the attention. But it's sad it's at another's expense.
Sounds like sibling rivalry being played out.
