£500? She's only 19 and very inexperienced. If you look at her photos, she just isn't beautiful enough to justify those prices.
I doubt if she gets any bookings.
It's fantasy pricing.
Beauty is subjective but the thinking some have that you get more beautiful WGs by paying more is another punting myth, i have punted with absolute stunners at parties and 121s for reasonable to me prices. At £350 an hour the WGs i punted with some years ago were no more beautiful to me than others i punted with at £100 an hour, in fact there was no difference at all, premises wise or in any other way.
She got at least one booking from the punter i mentioned previously but i definitely agree its fantasy pricing but she only needs a couple or few punters a week, perhaps she gets them.
