Jennie doesn't need to say anything as her badge does it for her. This reminds me when catching a bus or visiting the super market; just two random selections in my everyday. For example when you entre a bus there stuck on the drivers door a notice announcing ‘welcome Aboard’ so there’s no need for that odd grumpy old bus driver to even open their mouths in recognition that he has passengers boarding his service, apologies for those smiling faced ones.
