Could this be the best use of QR codes in history? The faked video clock had me thinking this never went ahead but the second Budweiser Nights video confirms it's real and they added the extra chance to win. The fact this clock is manned answered my other question about people cheating the system. The QR code here serves as a more interesting way essentially press a button.
Not only is this on brand but serves as an interesting utility and talking point at the bar.
