Port to Everywhere - Dresden Files
One interesting way that Kyoko’s family uses the restaurant is in the handling of secret messages. When someone calls for take out or delivery, they might add on a special code phrase that means they are interested in some kind of intelligence or aid. Kyoko’s father will then enchant one of the paper bags or cartons used for their meal with a special message that only someone who knows the password can access. Customers will then pay for their meal and tack on a generous tip for the information. Sometimes when the need is urgent, Kyoko or her brother will deliver the message personally. Kyoko has been known to act as a carry pigeon at times as well.
