Asked for money for food in Liverpool centre

I was in Liverpool recently and a young woman approached me directly but timidly asking for money for food. I politely declined, and she took it politely. I'm aware that sometimes these can be scams, or even worse a setup for pickpocketing. I live in a smallish town and don't really spend time in cities these days, and things have gotten much harder for everyone since I did. If someone was generally in need of food I'd of course help them if I'm able. I'm also aware that my willingness to help can be abused too sometimes.

Anyway, just wondering if you guys had any more insight into it. Did I fail to help a young person in need, or did I avoid a common scam?
