L only did it once that I know of, and it was after she'd moved to the other state and had forgotten about the time changing (because we don't go on daylight savings time in AZ). She may have done it other times but rescheduled the other person and not told me, no way of knowing.

I don't think I would be very forgiving at all (even of L whom we all know I adore) if she checked her email during a session (which is bad enough) and then interrupted me while I was already talking and said oops, nevermind I can't meet today after all I have to go meet with other therapists. If she was suddenly ill, or got an emergency call from a family member, that would be one thing but this would really irk me.

One time somebody knocked on her door during my session and she made sure I was okay with her answering it which of course I was just in case it was an emergency, excused herself, went and opened the door and pretty much told them off whoever it was. Definitely a side of her I'd never seen before! She has a sign on her door clearly indicating 'in session do not disturb'.
