That is entirely up to the lady. My ATF and I have been seeing each other for a number of years; I've never asked for a lower rate, and she's never offered one - her rate is reasonable, especially for the services she provides.
If people I had grandfathered in after seeing them the 10+ years I have been in the trade or the 5 I've been Indy, they stay at a special rate. They always get more time because I enjoy them immensely on a platonic level as well. Biomed knows this.
If I happen to run a special, then they get a .50 off of hr rate.
