man: “ID? I’m not giving you my ID.”
me: “We’ll also take a credit card, basically anything we can use to hunt you down in case you forget to return them.”
man: (appalled) “This is ridiculous. I’m not giving you my drivers license. What if this building burns down. Then I’ll be without my license.”
me: “Well, you probably won’t need your license if the building burns down.”

Because you will be dead.
