"she was starting to well up at one point so she did seem desperate, even if the story was rubbish - she didn't have an obvious drug vibe though." Unfortunately, that's all part of the act. It was quite common when we lived in Brixton a few years ago - maybe they've burned out their welcome there. Some other scams: Distraught woman, crying fit to burst, claiming to have been attacked, bleeding from where she's picked at her scabs. Smartly dressed person claiming to need money for petrol - can't remember what the excuse was. Asking for money for travel ticket to get home, to Brighton or similar, because they've been robbed. Man asking for ?1 in exchange for a handful of coins, when you get your coins out to see whether you've got one, he swiftly scoops the lot and makes off.
