I find it quite amusing looking back at reviews of popular girls from only 2 0r 3 years ago where people were complaining that £130 - £150 / hour was too expensive and they would never pay that rate.
Now those same girls are charging £220 - £250 and presumably getting all the business they need.
In our company we have had to raise our prices by at least 30% and we've never been so busy despite wages not keeping up.
It's interesting how our perspective of what the price of services should be migrates over time.
For me at least, the price is a little less important and when I have a poor experience it's the waste of time and the disappointment that I regret rather than the money.
