That sucks, and she should have either made up the time or not charged you. A few months ago, my marriage counselor said a the start of an appointment that he could only stay for 20 minutes because an emergency had come up (I got the sense it may have been personal but wasn't sure). He apologized and said he would never charge us for just 20 minutes (we'd already paid, so he gave us the next session for free) and wasn't sure if he should have just cancelled. But I was in a bad place at the time and was really glad he still saw us--I just jumped right to what was upsetting me instead of the usual small talk/relaying what had happened in the past week. It was actually a really useful session. But if he'd made us pay for it and didn't seem apologetic, I probably would have been upset. Especially if I knew it was about a client, since it would seem he was choosing that person over us. So I get what you're feeling. You should definitely bring it up with T next session or maybe in e-mail before that.
