For awhile there the British pound was two to one versus the American dollar= one pound got you two American dollars. And if I worked in Belfast where the going rate was 100punds for 30mins., I could have charged 50pounds for the 30mins, because I would have made it up once I got to America, let alone my dollars would have gone further spendingwise in Amerca because things are less expensive here.
And further more, I doubt seriously that she gets many clients who'll avail of her services for that price, more than likely clients will feel sorry for her and pay more just so they don't feel guity about taking advantage of her. Plus she might be engaging in piecemeal pricing and charge for extras everythng-If I know there's loads of girls in a place that there was money to be made, I'd hope i'd have the sense to make the most of my earning potential and fuck what the going rate was and get what I could at a price that would get me the most money.
There's girls in New York city, Brazilans, doing $40 quickies, so this '40' is standard no matter what the currencies is-it's all about what you can 'buy' with the '40' that people aree thinking about.
I use to have the same views as alot of the escorts about 'below' the market rates, but I've meet some of the working girls here in America, and they are stunning, and you would think make fortunes, but no they don't make alot, and resort to doing $80 car-dates, go out on the streets or work a strip-club where they get clients and charge them $40 a pop to get their money.
