Yes I think they're always trying to screw more money out of us but it's up to us where we draw the line. We're the ones with the money. I'd emailed a WG recently, she replied promptly and I decided to see her when I was next in her area. When I was about to make the booking I saw she'd increased her rates from £80 to £100! I promptly wrote back and said thanks but no thanks. Very soon afterwards her rates came back down to £80 but she's lost me as a potential client. This is what we have to do as it's about the only language they understand.
