ES:
Using the services of a prostitute is not an offence. (Only 'kerb crawling' is).
Similarly the woman (or man, where appropriate) providing such services isn't directly committing an offence. Charging for sex is perfectly legal. However 'soliciting' and 'living off immoral earnings' aren't.
Ron:
What about AB's valued contributor, Barmaid?
She spend a great deal of time in the company of people who do soliciting, and she's never far from a bar. She's even proud of her ASBO!

PS: Before Barmaid sues me for defamation, I'll hastily point out that she's a barrister (who naturally associates with solicitors, and who works at the bar). ASBO is her cat ;-)
