My punting has almost hit zero. Whereas I was quite happy to take a chance at 60/70/80 quid, and just chalk it up to experience if it was crap, at 100+ I just don't feel the need to take a chance. I can still see a couple of regulars who have kept their prices under control, but most of my hobby now is parties and swingers clubs in the UK or abroad where some fun can always be guaranteed for a reasonable price.
I guess if the girls up their prices by 40% and lose 40% of their clients, why would they care?
