Tis a scam. I have had a woman with baby on the door needing money for the electric meter to heat the milk for baby. Gave her a tenner and of course never seen her again. It's a shame-scammed once but never give money anymore in such circumstances. In 2007 there was a woman, about 30ish who waved me down. Floods of tears, needed money to heat baby milk(again). I gave her a tenner, she stuck her head in through the car window saying ?you have more than a tenner you give me more? I said I also had children to feed. I had to threaten to drive away with her head in the car to get rid of her. She could have got a job as an actor.
