what happens if you rm rf root in apple store

what happens if you run `rm -rf /` on macbook or imac or macpro in apple store

do they sue you or you have to sit there with engineer recovering mac as a punishment

or is there a fee for doing that like penalty where you have to pay 1/10th of price of product

or do they take you to secret meeting dark room with auto opening electronic door

I wonder how many people actually did that

also what happens if you try to jailbreak iphone in apple store
