Wow. I would have been upset and confused waiting for that long. I'm assuming you didn't get any message that your session would be that delayed?

My T is often late, by a few minutes. Once in a while she will go over 10-15 minutes. Those times she always sends me a text apologizing and letting me know it won't be much longer.
Not ideal at all
BUT over the years, she has absolutely stayed with me post my time when I needed.

I don't think I could tolerate really prolonged lateness.
Did this happen just once? Or repeatedly?
