Ok, ok, ok!!!!!!!!!!
I admit, I posted this before I read the Walk-up thread and reading the OP explaining what it was (I know...... My bad!!!!!).
I genuinely didn't know what a Walk-up was, hence why I posted this question asking about this.
I must say that from reading the OP, this is something that I will never engage in.
I will stick to visiting Soho to go into sex shops and browse through the porn mags (which BTW I don't regard as lunatic behaviour as that is something I enjoy and will continue to do so)!!!!!!!!!!!!!
