Replying to MY invention

while enjoying a few brews at the Perpetual groove concert last night and wondering what my BAC was, i came up with a fantastic idea.

BREATHALIZERS IN ATM MACHINES- ATM MACHINES ARE EVERY WHERE SO WHY NOT PUT IN A BREATHALIZER IN THERE, AND CHARGE 75 CENTS PER PUFF...the Part where you put your mouth would have a plastic disposable lining like what covers modern thermometer...Id make millions bithces if i had one on every block in every college town/bar area in the US
