Here's the thing: 1. Homeless people are screwed by society in almost every possible way. 2. There are a million ways to get free food when you're homeless. I.e. hunger is a solved problem for most homeless people. With this context in mind, you can see how offering someone your half-eaten leftovers, or forcing them to go on some journey with you in exchange for a basic meal, is not only unhelpful--it's downright insulting. If you don't feel comfortable giving them money, or engaging in an honest conversation, then just say sorry and walk away. And if you feel like you want to help homeless people without giving them money, then give the money to an organization instead. The bottom line: don't expect homeless people to be grateful to you, especially if what you're offering is next to nothing for them.
