First:
I like RBs, I've had a geat success with them.
Second:
What a girl bids and where she is based can be irrelevant.
Third:
I have written up my experiences and posted on here, a use of the Search function will find it.
To explain my 'second.'
I had a response to a £300 incall to my Cardiff apartment from a, now retired, lady who normally charged £1500 for an overnight and was based in the north of England.
I accepted but asked why?
She clearly explained that she was planning a south Wales tour to Cardiff. My RB gave her £300 in her expenses pocket and would pay for her travel and hotel bill for the tour.
So she could make the tour date and not worry if she didn't get the number of 30/60 minute bookings that she needed to cover the expenses.
Seemed like a good business move to me!
