Can I ask how late your T is? Mine is often 5 minutes late, if I'm looking at the exact time on my phone. But she always keeps me the full time.

Meanwhile, my marriage counselor is typically anywhere from 5 to 20 minutes late. I've gotten used to it and come to accept it (partly because I am pretty attached to him). He'll give clients more time when they need it, and that's happened multiple times with H and I. So I figure I can allow for other clients to run over, as they probably need it.

So I think it depends on how late she is, and why. And also whether she's apologetic at all. Any chance you could get either her first appointment in the morning or the first one after her lunch break? Then there might be less of a chance of her running late.
