Plan A fell through and whilst in the car on the way I managed to arrange a Plan B (it was a 2 hour journey). Plan A was £120 and I had it counted out and ready, so when I arrived at Plan B I gave her the £120, but forgot that she was only £100, so she gave me back £20. Bugger me if the next visit she hadn't put her prices up to £120!! Apologies to everyone else if I unintentionally gave her the idea.
(It was Emily@19 in Birmingham, but don't send me the bill for the difference if you've seen her since!)
