West Belfast Style

Paddy from the Falls Road in Belfast goes into a brothel in Amsterdam and finds himself a prostitute. He asks her,
"How much do you charge for the hour?"
"£100," she replies.
So he asks,
"Okay do you do West Belfast style?"
She says "No!"
He then asks her,
"I'll pay you £200 to do it West Belfast style?"
She again says no, not knowing what West Belfast style was!
So he then offers her £300. Again she declines his offer. So finally he says,
"I'll give you £500 to go West Belfast style with me!"
Finally she agrees thinking, 'Well I've been in the game for over 10 years now, I've been there and done that, had every kind of request from weirdo's from every corner of the world. How bad could West Belfast style be?'
So she goes ahead and has sex with him, doing it in every kind of way and in every possible position. Finally, after several intense hours they finish. Exhausted, the hooker turns to him and says,
"That was fantastic. I've never enjoyed it so much. But I was expecting something perverted and disgusting. Where does the 'West Belfast style' come in?"
Paddy replies . . .
"I'll pay you next week"
