At a hardware store
Woman: What are you doing. Don’t do that. You’ll destroy the shelves.
Man: Destroy?
Woman: Yes, you’ll destroy the shelves. You make a mess of them.
Man: Oh, I don’t want to make a mess of the shelves.
Man: I just want to try this electric saw.
Woman: Well, unplug the drill and plug the saw in.

You make a mess of them.
What does “You make a mess of them” mean in this dialogue?
Does it mean “You destroy them” or something else?
Thank you
