If he were the sort of man to get offended easily, Batman might have taken offense that his only value to them seem to be his knowledge of Gotham's dangers, and how to combat them if and when they seeped beyond the edges of his domain. He really didn't care though, and it told him what he was working with.
He did appreciate that Hill didn't take him for a fool and try to bulldoze him on the catch, but as Batman suspected, it was exactly the price he wasn't ever going to pay.
Batman snorted softly in derision. They might, one day, discover his identity, but it would never be because he simply handed it to them. "Not interested," he said, turning back toward the edge of the roof.
