Banta, forgive me, i don't know how to copy and paste your comment, so i can reply.
You asked why? Well in my punting experience, i found it a common practice that girls from certain countries will offer things at discretion, when it was never on the menu. And sometimes punters will get whats on the menu, and maybe more if the girl likes you.
Now in regards to this provider, if you do due diligence on her, it is very plain to see, she doesn't really provide OWO or DFK, two things which make or break a punt for a lot of people, me included.
Now, if i read a punter got something that she doesn't normally provide, i would ask the provider, if i was interested in seeing her, if she definitely provided that service. I would let them know that i would be walking, if they came out with some last minute excuse as to why they can't provide a specific service. So, as not to waste each others time, what's it to be. And i found in most cases they will be straight with you.
I know it's frustrating, and irritating, and in an ideal world, every like, on the likes list, was delivered as is stated, without being upsold, or being given some lame excuse, as to why they can't do something.
Just to add, i find a lot of the Rom girls really beautiful, and i know there are probably a lot of good ones out there, but the majority don't provide the services i want and like. Which is a bummer
