Beating a dead horse here...
Obviously it's up to the girl to decide what she offers or not, but if she's going to make her menu a la carte it should be posted on her profile page. This is true for other aamp around the country. The upcharges are posted.
This game operates on some assumptions. Otherwise I'd drop the donation and then just look at her?
Every scene is different, and from my experience in the bay with k girls, the rate includes all the trimmings.
Unless posted otherwise, why would a monger assume it isn't? Historically it's been that way. It just seems shady to not post upcharges if they are there. Even Indy girls post their upcharges.
