I thought this was an interesting little experiment.
"Over the past two weeks, I wandered Toronto’s downtown core with five prepaid Visa and MasterCard gift cards, in $50 and $75 denominations, waiting for people to ask for money.
When they did, I asked them what they needed. A meal at a restaurant, groceries, a new pair of pants, they said. I handed out the cards and asked that they give them back when they’d finished shopping. I either waited at a coffee shop while they shopped or — in the case of those who could not buy what they needed nearby or were reticent about leaving their panhandling post — I said I’d return on another day to pick up the card. That’s when I would reveal that I was a journalist."
