He was inside starbucks and was walking out the door while I was waiting for a chance to enter. He stopped me and told me his name was Marcus, he was really hungry and needed some money for food. I gave him what was in my pocket, about ~2 bucks. He took it, looked at me and said "That's it?". He scoffed and walked away.
