A real breadstick will just spoil eventually, or be gone once eaten. I recommend gifting him the NFT of a breadstick instead, it will never spoil, and with that he will be able to show everyone that he owns a breadstick (somewhere). With that the possibilities are endless, other restaurants could use that to verify that he does, indeed, own a breadstick, and give him real breadsticks for free!
Sure someone could eat the breadstick, but let's focus on what's important here, just because someone eats the breadstick doesn't mean they own the breadstick!
