While I can understand having something you planned out fall through be disappointing, I truly hope this thread wasn't intended to put the provider down.
Any provider who gives me notice (prior to me leaving to see her) is A ok in my book. Better than me arriving and no one answering the door or my phonecalls or having a crappy session.
If you're worried about having fun today or this weekend I wouldn't worry about it. There are literally thousands of people, places, or events that would gladly take your money
