PSA: Potential door-to-door 'COVID' money-begging scam

I was bringing in the garbage bins this afternoon, and just after I'd done that and gone upstairs, someone both knocked on my door and rang the doorbell. I went downstairs to see what their business was, and a woman was standing on the stairs coming up to my verandah (screen door, not main door) with a younger male behind her, both wearing masks and keeping distance.

I asked her business, and she said her family had been hit hard by COVID, and she was going around trying to raise money for food. I told her I couldn't help her (as in give her money), which was the truth as I'm on ODSP and I usually have just enough to make ends meet. She left when I told her I couldn't help, and her final words were 'Good luck!', which was also a bit strange.

Her manner during the conversation and the way she tried to ask me for money without using the word 'money', that her interest dropped like a rock when I told her matter-of-factly I had nothing to spare, and the interaction altogether just seemed fishy and scammy, whether or not it was. It's the only time something like this has happened to me, or at my door.

Posting this to give a heads-up if someone like this is coming to anyone else's doorstep, and I would be very interested in hearing if this has happened to anyone else prior to the visit to my own door.
