If you want to shut him down a bit quick whenever you are stone cold sober... get a little BAC tracker. Blow in front of him. Then tell to kick rocks and get off your back. This is the one I got. Kinda just to see where I'm at and as a funny party thing. My best friend is a sheriff deputy and we tested one night drinking along with his BAC track.(same one) and it was with in a few 0.00X and we were like ok good enough to me to get a good gauge. https://a.co/d/032DMqTD
