I get this a lot also. I will never open my wallet for the homeless, but I will clear out my cupholder of any change if I have it. Usually if it's a veteran or disable homeless person. Also, I usually always have bottled water in my jeep and have given those out too. Once, in Santa Monica CA, I was at a jack in the box drive thru with a homeless man standing at the order speaker. I told him I didn't have cash, but bought him a $1 burger and looped around to give it to him. Thought I would make his day. He proceeded to spike the wrapped burger off the hood of my Mazda at the time, and screamed, "I didn't ask for a fuckin burger, did I?" Last time I will ever do that lol
