ive seen them in the UK, Germany and Amsterdam. Approx numbers:
UK - 4 out of 6 rip off. Bait & switch and shit service
Amsterdam RLD -5 for 5 rip off. I don't even bother going back any more.
Germany FKK - 8 out of 10 good.
That said, even though the FKK ones are good, they are still missing something. They are quite hard nosed sex workers, no connection. Though they are Ok they are also quite forgettable.
Romanians are kind of taking over the scene across Europe. I can't even be arsed with FKK anymore as they are all Romanian barbies who although quite fit and willing are too clinical for me.
