Anth, you could try, but I think you are wise enough to know it depends completely on the girl, not on any general answer anyone else could possibly give (unless perhaps they knew/know her). I've done it a couple of times but check out the situation: when she saw you before she was regularly in "prossie" mode and doing a nice act. I've had a couple who did it for nowt after a lot of chat, ie a "civvie" punt; but one I recall that went a bit the other way was a prossie I was very friendly with, lovely girl and a regular. She gave it up partly on account of a boyfriend partly on account of a straight job. I persuaded her back for a punt and it was ok, but there was also the awareness that she was a decent looking 19yr nearly 20, into clubbing, Ibiza, meeting guys her own age and to hang out with, that our friendship, what there was of it, was based mostly on her being a working prossie as that is how I knew her. So why the fuck was she shagging some old guy for a petty £60? It's not something a civvie does. If she's no longer a working girl then the pretend act has possibly worn off and she doesn't really know why she's doing it except she's a bit confused. Either way, unless she is really expert in her own mind at changing lanes it's not such an enthusiastic fuck.
