One time I was walking around downtown wearing a dress shirt & dress pants, so I guess I looked like I had money, and I was approached by a homeless person who wanted me to buy him food. I pretended to misunderstand his request and, in a helpful tone, told him that there was a McDonald's nearby and he could get a meal there. I put my earbuds back in and kept walking as he yelled 'No! Can you /buy/ me food?!'
