I think you're taking the P!SS, Steve2!
Are you suggesting that middle class blokes sit on the wall outside the post office, waiting to strike up conversations with a young mum and a couple of bin lids in tow and then subtly offers her an "arrangement"?
I don't get it... I don't really see how these things can come about in the way you say.
I would be genuinely interested in hearing how it came about for you and the other guy (Rain_Man) posting on here.
