I had a wonderful session with a lovely provider today.  I had booked a 1 hour session but could only hang out for about 40 minutes due to some other obligations.  The provider refunded me the difference between the 1/2 hour and the full hour session.  I will not name the provider because I don't want her to have others start demanding the same treatment, but I just thought it was a very nice and appreciated gesture.

Nope...don't want to rub anything yet.  Now when a provider returns all over my money because I gave the greatest 90 seconds of her life...well I will rub that in
