being made to feel ashamed

So she wasn't really double-booked then. Or did she kick the other fella out?
Either way, she should have contacted you rather than waiting for you to contact her.

Very good point that Ann
unless of course she had already phoned the other one , but I find that a bit doubtful

There will always be people who take the piss. If they can't afford your services then they should either save up like we all do when we want something, or look for someone else who fits their budget.
The thing is - if you were booking a hotel or buying a tv - you wouldn't go whining that it was out of your budget, you would most likely save to get what you wanted or look around at other options. Booking a service is no different and you shouldn't feel bad that everyone can't afford your service.
