Twas 1980, as I walked out of a pub in Plymouth my eye was caught by a sexy looking girl, I smiled at her, she smiled back, she followed me out into the street enquiring "are you looking for business ?" -- I was shocked but in an instant replied "how much ?",
she said "£12" and that was my first punt.
Forgot to add the reason ------ I was horny,and she was a bargain.
