EbonyAmber is right.
Plus any 'girls' advertising 'A' will charge more for it - it is not included in their 'standard' rate (with honourable exceptions)!
So if you compare a TS's standard rate to that of a lady offering 'A' I think you will find that it is much the same.
Either way all of the girls on this site earn every penny they make imho.
