I think it is hurting most hobbying budgets. But it is probally just making clients cut down on visits but not stop.
By the looks of some threads the local girls are still finding the schedule's full. So maybe instead of 25 clients a week, it is more like 20. At certain times of the year it also slows down.
I doubt the local SPs are affected too bad. After all, they have been increasing their rates.
