Just throwing this out there.
Do you think there is a direct correlation between trafficked EE girls and poor services?
My logic is as follows, the girl is trafficked so she doesn't want to work and doesn't see the money that is paid by clients hence the lack lustre service.
Depending on your taste in WGs there are some stunning EE girls out there that really are "money making machines" if they upped their service quality. Given many girls looks they would have guys crawling over each other to give them their hard earned cash!
