@Blickers,
Blinkers, she is being given "the business" because she is asking a foolish, and actually pretty insulting to the homeless, question.
She is asking what time an entire segment of the population, all individuals, go to bed?
You yourself said some really jacked up stuff assuming that someone without a residence must either go to sleep early, or else they are engaging in illegal activities.
The homeless have jobs, things to do, places to go, people to see, just like everyone else. To assume they crawl into a hole or box somewhere when the sun goes down, is insulting.
The fact is, finding food is the least of the issues facing the homeless. In a city of any size there are multiple places where meals can be found, clothes given out, etc.
The bigger problem is finding safe shelter where their stuff won't be stolen, and they won't get beat up, raped etc.
Of course they will be grateful if someone comes by with a hot meal. People aren't stupid and know to say thanks and accept free stuff. Not just for the immediate gift, but if a person shins a gift now, will end up keeping someone from giving them what they really need in the future.
Right now, with cold weather here, a good bet would be blankets for those who choose to stay on the street at night. Shelters can be some of the least safest places to be, as decent people will be placed in with the thieves, the violent, the drug addicts.
