Sounds like she wanted a bit of cock
I was gobsmacked! I just thought "cheeky cow", but couldn't say anything as she walked off somewhere straight away never to be seen again.
I think it should be automatic, they're no good to you once your gone!
I have no idea why people say shite like "you must be cold/hot...". I mean, I didn't just arrive from outer space, its the same focking temperature for me as it is for you! I guess its unnecessary small talk for strangers. ).
But I do think you should have to 'opt out' with a reasonable excuse rather than expressing your interest onto the register by carrying a card. That in itself would save even more lives, and I'm all for saving lives.
