She owes you a session. Plain and simple. Perhaps you should've given her a portion of the donation for having to leave abruptly. But still, being so loyal and "safe" she runs the risk of losing a regular client.

For the inconvenience, yes, I would have given her half. Unfortunately, you took a loss this time. If this should happen again, I would cement a SOLID understanding of the donation given for the next appointment. Hope this helps!
