I've given money - also went to buy someone sandwiches. One time a guy had a dog and I bought a bag of dog food.Yes - I saw it way back in the "old days" when it was first out - even my parents got a kick out of it.
It you saw someone on the side of the street with a sign that said they were hungry, would you give them something (e.g. When you are stuck at a red light and they have you as a "captive audience")?
Do you donate to charities?
