The man who fed the Ants

I saw this man today, throwing flour to the ground. Curious, I went and asked him what exactly is he doing? He said “feeding ants can’t you see? Now move away before you step on few of them. I was about to say, “The ants will survive without your help. They will manage quite well”. Then thought ants will survive without him but would he after knowing that the Ants actually don’t need him?
