To the OP.....I must admit I'm a little surprised there has been no reaction to your disclosing the name of the Domme in question. Perhaps because it's buried in the middle of the thread it wasn't noticed?

I don't think this issue is a huge or egregious offense on her part but it does seem to display a certain lack of respect for her clientele. Especially as you say you made 3 requests to have the deposit refunded after she cancelled the booking.

I would think the more high profile a Domme is the more likely she has subs travelling especially to see her. Last minute cancelations on her part part (unless absolutely unavoidable) seem poor behaviour and quite disrespectful.
